Question

Q15. Mention any three methods adopted by plants to minimise the transpiration rate.​

Answer 1

Answer:

Plants reduce water loss by closing their stomata, developing thick cuticles, or by possessing leaf hairs to increase the boundary layer.

Answer 2

Some plant species have stomata on both sides of the leaf while others have stomata on the lower leaf surface to minimize water loss. Special cells called guard cells control each pore's opening or closing. When stomata are open, transpiration rates increase; when they are closed, transpiration rates decrease.
