251 against a target of 290, and nine below the danger line. This is your lowest of the three papers, and it is worth being clear about why: thirteen errors, and seven of them are two habits. Five are statement questions where exactly one false statement was let through. Two are Assertion–Reason questions where a true reason was accepted as the right reason. Neither is a gap in anatomy — both are a reading step that was skipped. Fix those two and the same paper is a 286.

Six easy marks lost twice in a row is not a coincidence and it is not difficulty — it is pace. The questions that make you slow down are the ones you get. Every single error below is on a question that could have been read more slowly.

Read those four rows together. On plain questions you are at 88 per cent, and you got every one of the seven negative stems, which is the format most students lose marks to. The damage is concentrated entirely in the two formats that ask you to make more than one judgement per question — and in both, the judgement that gets skipped is the last one.
What actually went wrong
Thirteen wrong and one left blank — 69 marks against a clean paper. They fall into four groups, and the first two account for seven of the thirteen.
25 marks · Q49, Q56, Q66, Q78, Q79
Statement questions: one false statement gets through every time
This is the biggest single thing on the paper. Fourteen questions ask you to judge a list of statements — either how many are correct or which combination is correct — and you lost five of them. In all five the failure is identical: you accepted one statement that is false.
Not one of these was a question where you missed the topic. Q49, Q56 and Q66 all turn on the same two pairs — open against closed (is there a cambium?) and exarch against endarch (root or stem?). Q78 and Q79 both turn on an exception written inside the NCERT sentence and quietly deleted by the statement. You chose option (C) on both of those, and both times (C) was the option that drops statement A and keeps the false one at the end.
On the other nine statement questions you were right. The difference is not knowledge, it is that these five were never checked statement by statement.
10 marks · Q45, Q55
Assertion–Reason: a true reason accepted as the right reason
There are eight Assertion–Reason questions and you answered (A) on seven of them. Five times (A) was right. But three of the eight were built so that A is true, R is true, and R still does not explain A — and on those three you scored one.
Q45: the cortex really is loosely packed, but loose packing would help water through, not block it; the block is the Casparian strip. Q55: root xylem really is exarch, but every root is exarch, so it cannot be what tells a dicot root from a monocot one. In both the first two judgements came out true and the third was never made.
The dashed line printed under every one of these questions — A: T/F — R true on its own? — A because R? — was left empty on all eight. That third box is the whole question.
15 marks · Q20, Q25, Q42
Figures read halfway
Nine questions on this paper carry a drawing that can be answered two ways, where a first clue narrows the field and a second clue decides. You lost three of the nine, and left a fourth (Q14) blank.
Q20 and Q25 deserve looking at together. They are the xylem figure and the phloem figure, and you picked R in both — and R is the fibre in both. Fibres are thick-walled, pointed and dead; they hold the plant up and carry nothing. Both questions asked which cell conducts. The eye is going to the most strongly drawn cell on the page instead of to the property named in the stem. Q42 is the same halfway reading: you stopped at a bundle that looked right and never applied “on the same radius”.
15 marks · Q41, Q53, Q80
Three on their own
Q41 is a matching question with two rows transposed — root hair and subsidiary cells exchanged — where reading the two sentences back to yourself would have untangled them. Q53 is a counting error: seven xylem arms counted as five, which flipped a monocot root into a dicot. Q80 is one reversed prefix, ab– read as ad–. Three different slips, nothing in common, and none of them about anatomy you do not know.
Question by question
Q14Simple permanent tissues · Collenchyma · hard · left blank
The three drawings show one tissue in three forms. Taking them in the order P, Q, R, the forms shown are
(A) angular, lacunar and lamellar
(B) lamellar, angular and lacunar
(C) lacunar, lamellar and angular
(D) angular, lamellar and lacunarCORRECT
Left blank — 0 marks, no penalty.
You put a mark beside this one and struck it out, and left all four options blank. That was not a bad decision — a blank costs 0 and a guess risks −1 — but the question was gettable from the drawings alone. P has the thickening piled up at the corners: angular. Q has it laid down in flat layers on the tangential walls: lamellar. R has it round small spaces: lacunar. Angular, lamellar, lacunar — and the words say what the pictures show.
Angle, layer, lacuna. Read the three pictures, then go to the list.
Q20Complex permanent tissues · Xylem elements · moderate · the fibre taken for the conducting cell
Of the four elements drawn, the one whose end walls carry perforations so that the cells form a continuous open pipe is
(A) QCORRECT
(B) P
(C) S
(D) R✓ YOUR ANSWER
Four xylem elements were drawn and you picked R, the fibre. The stem gave you one property and one only: end walls carrying perforations, so that the cells form a continuous open pipe. R is long, pointed and very thick-walled — that is a xylem fibre, and a fibre is for support, not for carrying anything. Q is the wide cell drawn with the end wall broken open. Nothing in the question asked which cell was strongest or longest; it asked which one was open at the ends.
Perforated end wall = vessel. Thick wall and pointed ends = fibre.
Q25Complex permanent tissues · Phloem elements · moderate · the fibre taken for the conducting cell
Of the four elements drawn, the one that has lost its nucleus yet goes on conducting food is
(A) S
(B) PCORRECT
(C) Q
(D) R✓ YOUR ANSWER
The same figure read the same way, one section later — and you picked R again, and R is again the fibre. The stem asked for the cell that has lost its nucleus and still conducts food. A phloem fibre is dead; it conducts nothing. The cell you wanted is P, the sieve tube element: no nucleus, perforated end wall, still carrying food. Q, right beside it, is the companion cell, which keeps its nucleus and does the housekeeping for P.
Sieve tube: no nucleus, still conducting. Companion cell: nucleus, next door.

(C) A-IV, B-III, C-I, D-II
(D) A-IV, B-II, C-III, D-I✓ YOUR ANSWER
Two of the four rows are right and you have transposed the other two. You gave B–II and C–III: subsidiary cells matched to a unicellular outgrowth that absorbs water, and root hair matched to epidermal cells lying around the guard cells. Read those two sentences back and they swap themselves: an outgrowth that absorbs water is a root hair, and the cells lying around the guard cells are the subsidiary cells. A and D you had right from the start.
Subsidiary cells sit around the guard cells. A root hair is one cell, sticking out.
Q42The ground and vascular tissue systems · Kinds of vascular bundle · moderate · the figure read halfway
Of the three bundles drawn, the one in which the xylem and the phloem lie on the same radius and which could still add new xylem and new phloem of its own is
(A) P✓ YOUR ANSWER
(B) QCORRECT
(C) R
(D) Q and R equally well
You chose P, and P is the radial bundle — its xylem and phloem are on different radii, alternating. The stem's first clue was on the same radius, which rules P out before you look any further. That leaves Q and R, and the stem gives a second clue to separate them: could still add new xylem and new phloem of its own. Only a bundle with a cambium can do that — the line of cells drawn between the xylem and the phloem in Q.
Conjoint = same radius. Open = has a cambium. Two clues, two decisions.
Q45The ground and vascular tissue systems · The cortex and the endodermis · moderate · a true reason accepted as the cause
Assertion (A): In a root, water creeping along the walls of the cortex cannot pass straight on into the pericycle. Reason (R): The cortical cells of a root are loosely packed and have large spaces between them.
A: T / F — ____ R true on its own? Y / N — ____ A because R? ____
(A) Both A and R are true and R is the correct explanation of A✓ YOUR ANSWER
(B) Both A and R are true but R is NOT the correct explanation of ACORRECT
(C) A is true but R is false
(D) A is false but R is true
You answered (A), that R is the correct explanation. Both statements are true, so A and B both look possible and the whole question turns on the third judgement: does R actually cause A? A says water creeping along the walls is stopped before the pericycle. R says the cortex is loosely packed with large spaces. Loose packing would let water through more easily, not less. What stops it is the Casparian strip in the endodermis — and R never mentions it.
Ask it as three questions: Is A true? Is R true? Does R cause A?
Q49The ground and vascular tissue systems · Classifying the bundles · easy · a false statement kept
Given below are five statements about vascular bundles. A. A radial bundle is the kind found in a root. B. In a conjoint bundle the xylem and the phloem lie on the same radius. C. A bundle with a cambium between its xylem and its phloem is said to be open. D. The vascular bundles of a monocot stem are open. E. In a dicot stem the vascular bundles are arranged in a ring. Choose the correct answer from the options given below:
(A) A, C, D and E only
(B) A, B, C and D only✓ YOUR ANSWER
(C) A, B, C and E onlyCORRECT
(D) B, C, D and E only
Four of the five statements are right and you have kept the wrong fourth. You took D — the vascular bundles of a monocot stem are open. They are closed. Open means a cambium is present between the xylem and the phloem, and a monocot stem has no cambium at all, which is why a monocot stem cannot thicken. The statement you dropped, E, is the ring of bundles in a dicot stem, and that one is correct.
Monocot stem: no cambium, so closed. Dicot stem: cambium, so open.
Q53The dicot root and the monocot root · Counting the xylem arms · easy · miscounted by two
The number of xylem arms in the section drawn, and the group to which the root therefore belongs, are
(A) six, and a dicotyledon
(B) five, and a dicotyledon✓ YOUR ANSWER
(C) eight, and a monocotyledon
(D) seven, and a monocotyledonCORRECT
This one is not biology, it is counting. There are seven black xylem arms in that section; you counted five. Seven is more than six, so the root is polyarch, and polyarch means monocotyledon — so the group follows automatically once the count is right. Five would have made it a dicot, which is exactly where your answer went. The whole question rested on one number.
Two to four arms = dicot. More than six = monocot. Touch each arm as you count.
Q55The dicot root and the monocot root · Exarch xylem · moderate · a true reason accepted as the cause
Assertion (A): The number of xylem bundles in a transverse section is used to tell a dicot root from a monocot root. Reason (R): The xylem of a root is exarch, with the protoxylem lying towards the periphery.
A: T / F — ____ R true on its own? Y / N — ____ A because R? ____
(A) Both A and R are true and R is the correct explanation of A✓ YOUR ANSWER
(B) Both A and R are true but R is NOT the correct explanation of ACORRECT
(C) A is true but R is false
(D) A is false but R is true
(A) again, and the same move as Q45. Both statements are true: the number of xylem bundles does separate the two roots, and root xylem is exarch. But exarch is true of every root, dicot and monocot alike. A fact that both groups share cannot be the reason for telling them apart. R here is not false and it is not irrelevant to roots — it is simply not the cause of A.
If a reason is true of both groups, it cannot be what distinguishes them.
Q56The dicot root and the monocot root · Features of the two roots · easy · one false statement counted in
How many of the following statements are correct? A. In a dicot root the xylem bundles are two to four in number. B. In a monocot root the pith is large and well developed. C. A monocot root has a cambium lying between its xylem and its phloem. D. The xylem of a root is endarch.
(A) Only one
(B) Only twoCORRECT
(C) Only three✓ YOUR ANSWER
(D) All four
Two of the four statements are correct; you counted three, so you have let one false statement through. The two false ones are C, that a monocot root has a cambium between its xylem and its phloem, and D, that the xylem of a root is endarch. There is no cambium in a monocot root, and root xylem is exarch — protoxylem outwards, metaxylem towards the centre. Endarch is the stem.
Root: exarch. Stem: endarch. Monocot root: no cambium.
Q66The dicot stem and the monocot stem · Features of the two stems · easy · one false statement counted in
How many of the following statements are correct? A. The hypodermis of a dicot stem is sclerenchymatous. B. The vascular bundles of a dicot stem are conjoint, open and arranged in a ring. C. A monocot stem has a well marked pith at its centre. D. The xylem of a monocot stem is exarch.
(A) Only oneCORRECT
(B) Only two✓ YOUR ANSWER
(C) Only three
(D) All four
One statement of the four is correct and you counted two, so again one false statement got through. Only B is right. A is false — the hypodermis of a dicot stem is collenchymatous, and it is the monocot stem whose hypodermis is sclerenchymatous. C is false — a monocot stem has no marked pith; its ground tissue is undifferentiated. D is false for the same reason as Q56, the other way round: stems are endarch.
Q78The dorsiventral leaf and the isobilateral leaf · The isobilateral leaf · easy · the exception deleted
Given below are five statements about an isobilateral leaf. A. Stomata are present on both of its surfaces. B. Its mesophyll is not divided into palisade and spongy tissue. C. Bulliform cells may be present in its upper epidermis. D. All its vascular bundles, including those of the main veins, are of the same size. E. Its vascular bundles are surrounded by a layer of thick-walled bundle sheath cells. Choose the correct answer from the options given below:
(A) A, B, C and E onlyCORRECT
(B) A, C, D and E only
(C) B, C, D and E only✓ YOUR ANSWER
(D) A, B, C and D only
You kept D and dropped A, and both moves cost you. D says all the bundles are the same size including those of the main veins. NCERT's wording is “near similar sizes… except in main veins” — the exception is written into the sentence, and the statement deletes it. A, which you dropped, is plainly true: an isobilateral leaf does have stomata on both surfaces. That is the one fact everybody knows about it.
Near similar — except the main veins. The exception is the question.
Q79The dorsiventral leaf and the isobilateral leaf · The leaf in general · easy · the exception deleted
Given below are five statements about the leaf. A. The epidermis of a leaf is usually covered with a cuticle. B. The size of a vascular bundle in a dicot leaf depends on the size of the vein it lies in. C. In a dorsiventral leaf the abaxial epidermis generally bears more stomata than the adaxial. D. The mesophyll is the ground tissue of the leaf and its cells contain chloroplasts. E. In an isobilateral leaf the adaxial epidermis bears no stomata at all. Choose the correct answer from the options given below:
(A) A, B, C and E only
(B) A, C, D and E only
(C) B, C, D and E only✓ YOUR ANSWER
(D) A, B, C and D onlyCORRECT
The same shape as Q78, and you chose option (C) on both: drop A, keep the last one. E says an isobilateral leaf has no stomata on its adaxial (upper) epidermis. It has them on both surfaces — that is what makes it isobilateral, and it is the same fact you dropped as statement A in the question just before. A here, the cuticle on the leaf epidermis, is true and routine.
Dorsiventral: stomata mostly below. Isobilateral: stomata on both.
Q80The dorsiventral leaf and the isobilateral leaf · Reading the surfaces backwards · hard · adaxial and abaxial reversed
NCERT calls the upper surface of a leaf the adaxial surface. Asked from the other end — a leaf whose stomata are the more numerous on the surface NCERT calls abaxial — is best described as
(A) dorsiventralCORRECT
(B) isobilateral✓ YOUR ANSWER
(C) a leaf with no bundle sheath
(D) a leaf with no cuticle
The hardest question on the paper and it comes down to one word. Abaxial means away from the axis — the lower surface. More stomata on the lower surface than on the upper is the dorsiventral pattern; you answered isobilateral, which is the leaf with roughly equal numbers on the two sides. The stem had already told you that adaxial is the upper surface, so abaxial had to be the other one.
ad– towards the axis = upper. ab– away from the axis = lower.
What to do before the next paper
On every statement question, mark each statement T or F in the margin before you look at the options Five letters, five marks, ten seconds. Every one of your five statement errors was a false statement that went unchallenged because the options were read first. This single habit is worth 25 marks on this paper.
Fill in the dashed Assertion–Reason line. All three boxes. It is printed under every A–R question for exactly this reason, and you left all eight empty. The third box — A because R? — is a separate question from the first two, and it is the only one that distinguishes (A) from (B). You answered (A) seven times out of eight; the paper only had five (A)s.
Learn these three pairs as pairs, and say both halves aloud Open / closed: open has a cambium (dicot stem), closed has none (monocot stem, monocot root). Exarch / endarch: root is exarch, stem is endarch. Collenchyma / sclerenchyma hypodermis: dicot stem collenchymatous, monocot stem sclerenchymatous. Five of your thirteen errors — Q42, Q49, Q55, Q56 and Q66 — turn on one of these three pairs.
On a figure question, underline the property the stem names before looking at the drawing Q20 and Q25 both named conducting and you both times chose the fibre, which is the thickest-drawn cell on the page. Underline the word first and the drawing stops leading you.
Use the response grid This is the third paper in a row where you have ticked the options on the question pages and left the 80-row grid blank. On the real NEET there are no options to tick — there is an OMR sheet and nothing else, and transferring 180 answers under time pressure is a skill of its own. Start using the grid now, while a mistake costs nothing.
What went right
Worth saying plainly, because the score does not show it. Meristematic tissues: eight out of eight.Every negative stem: seven out of seven.Fourteen of the sixteen hard questions. The dicot and monocot stem block, nine out of ten. You also left Q14 blank rather than guessing at it, which is the right call under a negative-marking scheme and is a discipline a lot of students never learn.
There is no chapter here that you do not know. The 39 marks between this and your target are sitting in two reading habits, and both are fixable in a week.
