Match List-I with List-II :
List-IList-II
A. Conjunctive tissueI. Specialised cells in the vicinity of guard cells
B. Casparian stripsII. Endodermal cells rich in starch
C. Subsidiary cellsIII. Tissue between xylem and phloem
D. Starch sheathIV. Endodermal cells with suberin deposition
Choose the correct answer from the options given below :

Solution & Explanation

Core Logic
  • Conjunctive tissue (A) is the parenchymatous tissue that lies between the xylem and phloem patches in roots. (A-III)
  • Casparian strips (B) are suberin depositions forming a water-impermeable band in the cell walls of endodermal cells. (B-IV)
  • Subsidiary cells (C) are specialized epidermal cells found adjacent to and supporting the guard cells in stomata. (C-I)
  • Starch sheath (D) is a term used for the endodermis in dicot stems because its cells are rich in starch grains. (D-II)
Step 1: Final Conclusion

The correct matches are A-III, B-IV, C-I, D-II.

Pattern Recognition

Casparian strips exclusively map to endodermal cells with suberin (B-IV). This immediately isolates the correct combinations, and subsidiary cells uniquely relate to stomata/guard cells (C-I).

Q102 neet_2026_03_may_morning Root Anatomy
In angiosperms, root hairs arise from which one of the following regions of the root?
  • A. The root cap zone
  • B. The region of meristematic activity
  • C. The region of elongation
  • D. The region of maturation

Solution

Core Logic

The root has several distinct zones starting from the apex:

  • Root cap zone
  • Region of meristematic activity
  • Region of elongation
  • Region of maturation

    • From the epidermal cells in the region of maturation, very fine and delicate, thread-like structures called root hairs emerge. They increase the surface area for water and mineral absorption.

Step 1: Final Conclusion

Root hairs arise from the region of maturation.

Pattern Recognition

Root hairs require fully differentiated epidermal cells, which only exist in the maturation zone. Elongation and meristematic zones possess dividing/growing cells without mature outgrowths.

Q107 neet_2026_03_may_morning Leaf Anatomy
The main function of bulliform cells in grasses is :
  • A. to make the leaf impermeable to fungal spores.
  • B. to perform photosynthesis.
  • C. to minimize water loss during water stress.
  • D. to transport water.

Solution

Core Logic

Bulliform cells are large, empty, colourless epidermal cells found on the adaxial surface of grass leaves. During water stress (scarcity), they lose water, become flaccid, and cause the leaves to curl inwards to minimize exposed surface area, thereby reducing water loss through transpiration.

Step 1: Final Conclusion

Their main function is to minimize water loss during water stress.

Pattern Recognition

Bulliform cells = Grass leaves rolling/curling = Water conservation mechanism.
