Question

Maximum transpiration takes place from

• A. Stem
• B. Leaves
• C. Roots
• D. Flowers and fruits

Answer 1

The correct option is B Leaves

Maximum transpiration takes place from leaves. It is known as foliar transpiration. The leaves have stomata. Stomata are small openings on the leaves which helps in transpiration and gaseous exchange. The cells of stomata are known as guard cell. The guard cells are bean or kidney shaped in surface view so it is known as reniform which literally means kidney shaped. When the stomata opens for transpiration, it also allows gaseous exchange.

So, the correct answer is option B.
