  • (A) Stomata
  • (B) Trichomes
  • (C) Pits
  • (D) Hydathodes
Correct Answer - Option(A)

Explanation by: Official MCQ Buddy

Stomata are tiny pores found on the surface of leaves (mainly on the lower epidermis) that regulate gas exchange and transpiration in plants. They allow the intake of carbon dioxide (CO₂) for photosynthesis and the release of oxygen (O₂) and water vapor.

Other options:

  • (B) Trichomes → Hair-like structures on the leaf surface that help in reducing water loss and protecting against herbivores.
  • (C) Pits → Depressions in the cell walls of xylem cells, aiding in water transport.
  • (D) Hydathodes → Pores on leaf edges that help in guttation (exudation of water).

Thus, stomata are the correct answer!
