Loss of water as **vapour** (transpiration) is highest in which type of tissue/structure on a typical dicot leaf?
ACuticle
BLenticels
CStomata (90–93% of total transpiration)
DTrichomes
Answer & Solution
Correct answer: C. Stomata (90–93% of total transpiration)
Stomatal transpiration ≈ 90–93%; cuticular ≈ 8–10%; lenticular ≈ 0.1–1%. Stomata are the main regulated route — they can be closed via ABA signalling during water stress.
