  • Trichomes are the epidermal outgrowths on the vegetative and reproductive parts of the plant.
  • These are hair-like structures which may be unicellular or multicellular.
  • Some trichomes are secretory in nature and are known as glandular trichomes. For example, tannins, resins, gum etc., are some products secreted by trichomes.
  • Trichomes help in the absorption of water and minerals.
It is not a leaf modification, hence, option A is incorrect. So, the correct answer is 'Trichomes are leaf modifications which minimize water loss'.
