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

Related Formula

Conjunctive tissue: Between xylem & phloem. Casparian strips: Suberin in endodermis. Subsidiary cells: Near guard cells. Starch sheath: Endodermis in dicot stem.

Core Logic
  • Conjunctive tissue: Parenchymatous tissue lying between xylem and phloem arrow III
  • Casparian strips: Suberin deposition on endodermal walls arrow IV
  • Subsidiary cells: Specialized epidermal cells surrounding guard cells arrow I
  • Starch sheath: Endodermis of dicot stem rich in starch grains arrow II
Step 1: Match Verification

Matching layout: A-III, B-IV, C-I, D-II. Option (3) is correct.

Pattern Recognition

Subsidiary cells = Vicinity of guard cells (C-I). Casparian strips = Suberin (B-IV). Matches option (3).

Q102 neet_2024_05_may_morning Root Anatomy and Root Hairs
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

Related Formula

Root Zones: Root Cap arrow Meristematic arrow Elongation arrow Maturation (Root Hairs).

Core Logic

In angiosperms, epidermal cells in the region of maturation differentiate into fine, unicellular tubular extensions called root hairs, which absorb water and minerals.

Step 1: Conclusion

Root hairs arise from the region of maturation. Correct option is (4).

Pattern Recognition

Root hairs = Region of Maturation.

Q107 neet_2024_05_may_morning Bulliform Cells Function
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

Related Formula

Bulliform cells (motor cells in monocot leaf epidermis): Flaccid (water stress) arrow Inward rolling of leaf arrow Reduced exposed surface area.

Core Logic

In grasses, large, empty, colorless epidermal cells called bulliform cells absorb water to become turgid (exposing leaf surface) and lose water under drought stress to become flaccid, causing the leaves to curl inward to minimize water loss.

Step 1: Conclusion

The main function is to minimize water loss during water stress. Option (3) is correct.

Pattern Recognition

Bulliform cells in grasses = Leaf curling = Minimize transpiration/water loss.
