Epidermal Hairs & Trichomes — NEET Biology
📚 Practice ConceptThe cells of epidermis bear a number of hairs. The root hairs are unicellular elongations of the epidermal cells and help absorb water and minerals from the soil. On the stem the epidermal hairs are called trichomes. The trichomes in the shoot system are usually multicellular. They may be branched or unbranched and soft or stiff. They may even be secretory. The trichomes help in preventing water loss due to transpiration.
Assertion (A): Root hairs and trichomes serve different functions in plant water management. Reason (R): Root hairs prevent water loss due to transpiration while trichomes absorb water and minerals from the soil.
View solution & NCERT explanation
Correct answer: C — If assertion is true but reason is false.
NCERT confirms that root hairs and trichomes have different water-related functions (Assertion true). However, NCERT states “The root hairs are unicellular elongations of the epidermal cells and help absorb water and minerals from the soil. The trichomes help in preventing water loss due to transpiration” - the Reason swaps the functions of these structures.
