Real NEET and AIPMT questions from this chapter, newest first. Try each one, then open the answer and the step-by-step explanation.

  1. Question 1 (NEET 2026)

    NEET 2026EasyLeaf Anatomy
    The main function of bulliform cells in grasses is:
    1. Option A: To make the leaf impermeable to fungal spores.
    2. Option B: To transport water.
    3. Option C: To perform photosynthesis.
    4. Option D: To minimize water loss during water stress.
    Show answer & explanation

    Correct answer: (D) To minimize water loss during water stress.

    Explanation

    Bulliform cells lose water during drought, causing leaves to roll inward and reduce exposed surface area, thereby minimizing water loss. Hence option (D) is correct.

  2. Question 2 (NEET 2026)

    NEET 2026MediumEndodermis, Casparian Strips and Plant Tissues
    Match List-I with List-II: Choose the correct answer from the options given below :
    1. Option A: A-IV, B-III, C-I, D-II
    2. Option B: A-III, B-IV, C-II, D-I
    3. Option C: A-III, B-IV, C-I, D-II
    4. Option D: A-IV, B-III, C-II, D-I
    Show answer & explanation

    Correct answer: (C) A-III, B-IV, C-I, D-II

    Explanation

    Conjunctive tissue lies between xylem and phloem. Casparian strips are suberin deposits in endodermal cells. Subsidiary cells occur adjacent to guard cells. Starch sheath refers to endodermal cells rich in starch.

  3. Question 3 (NEET 2021)

    NEET 2021MediumTissue System
    Select the correct pair.
    1. Option A: Loose parenchyma cells rupturing epidermis and forming lens-shaped opening in bark — Spongy parenchyma
    2. Option B: Large colourless empty cells in epidermis of grass leaves — Subsidiary cells
    3. Option C: In dicot leaves, vascular bundles are surrounded by large thick-walled cells — Conjunctive tissue
    4. Option D: Cells of medullary rays that form part of cambial ring — Interfascicular cambium
    Show answer & explanation

    Correct answer: (D) Cells of medullary rays that form part of cambial ring — Interfascicular cambium

    Explanation

    Interfascicular cambium develops from medullary ray cells and forms part of the cambial ring. Other pairs are incorrectly matched.

  4. Question 4 (NEET 2018)

    NEET 2018EasyLeaf Anatomy
    Stomata in grass leaf are:
    1. Option A: Dumb-bell shaped
    2. Option B: Kidney shaped
    3. Option C: Barrel shaped
    4. Option D: Rectangular
    Show answer & explanation

    Correct answer: (A) Dumb-bell shaped

    Explanation

    Grass is a monocot plant and monocot leaves possess dumb-bell shaped guard cells. Hence, option (A) is correct.

  5. Question 5 (NEET 2018)

    NEET 2018EasyRoot Anatomy
    Pneumatophores occur in
    1. Option A: Halophytes
    2. Option B: Free-floating hydrophytes
    3. Option C: Submerged hydrophytes
    4. Option D: Carnivorous plants
    Show answer & explanation

    Correct answer: (A) Halophytes

    Explanation

    Halophytes such as mangroves possess pneumatophores, which are negatively geotropic roots that help in gaseous exchange in marshy habitats. Hence, option (A) is correct.

  6. Question 6 (NEET 2018)

    NEET 2018EasyStem Anatomy
    Plants having little or no secondary growth are
    1. Option A: Grasses
    2. Option B: Deciduous angiosperms
    3. Option C: Cycads
    4. Option D: Conifers
    Show answer & explanation

    Correct answer: (A) Grasses

    Explanation

    Grasses are monocotyledonous plants and monocots generally show little or no secondary growth. Hence, option (A) is correct.

  7. Question 7 (NEET 2018)

    NEET 2018EasyTissue System
    Casparian strips occur in
    1. Option A: Epidermis
    2. Option B: Pericycle
    3. Option C: Endodermis
    4. Option D: Cortex
    Show answer & explanation

    Correct answer: (C) Endodermis

    Explanation

    Casparian strips are present in the radial and tangential walls of endodermal cells. These strips are made of suberin and regulate water movement. Hence, option (C) is correct.

  8. Question 8 (NEET 2018)

    NEET 2018EasyStem Anatomy
    Secondary xylem and phloem in dicot stem are produced by
    1. Option A: Apical meristems
    2. Option B: Vascular cambium
    3. Option C: Axillary meristems
    4. Option D: Phellogen
    Show answer & explanation

    Correct answer: (B) Vascular cambium

    Explanation

    Vascular cambium is a lateral meristem responsible for producing secondary xylem towards the inside and secondary phloem towards the outside. Hence, option (B) is correct.

  9. Question 9 (NEET 2016)

    NEET 2016EasyStem Anatomy
    The balloon-shaped structures called tyloses
    1. Option A: Originate in the lumen of vessels
    2. Option B: Characterize the sapwood
    3. Option C: Are extensions of xylem parenchyma cells into vessels
    4. Option D: Are linked to the ascent of sap through xylem vessels
    Show answer & explanation

    Correct answer: (C) Are extensions of xylem parenchyma cells into vessels

    Explanation

    Tyloses are balloon-shaped outgrowths of xylem parenchyma cells that protrude into vessel cavities and help block vessels during heartwood formation.

  10. Question 10 (AIPMT 2014)

    AIPMT 2014MediumDicot and Monocot Anatomy
    You are given a fairly old piece of dicot stem and a dicot root. Which of the following anatomical structures will you use to distinguish between the two?
    1. Option A: Secondary xylem
    2. Option B: Secondary phloem
    3. Option C: Protoxylem
    4. Option D: Cortical cells
    Show answer & explanation

    Correct answer: (C) Protoxylem

    Explanation

    The orientation of protoxylem helps distinguish stems and roots. Dicot stems are endarch (protoxylem towards the center), whereas dicot roots are exarch (protoxylem towards the periphery).
