Question

Complete the following statement by choosing the correct option out of those given within brackets.
90% of the total water is lost through (cuticle/stomata/lenticel).

Answer 1

Transpiration

1. Transpiration is an essential process of eliminating the excess amount of water from the plant's aerial parts.
2. Plants lose water in gaseous form or vapor form through stomata in the process of transpiration.
3. Plants lose water through stomata, lenticels, water stomata, or hydathodes.
4. The maximum amount of water is lost by the stomatal transpiration i.e., 50-90% water of total transpiration.
5. Some amount of water may be lost through lenticels, bark, and cuticle.
6. Water is lost in liquid form through hydathodes.

Final answer: 90% of the total water is lost through stomata.
