Question

why upper surface of leaf has fewer stomata

Answer 1



the upper part of leaf have fewer stomata because on the upper part they are more exposed to sunlight and wind. There are many stomata at the lower part because it reduces the rate of evaporation as their is no much sunlight reaching their.

Answer 2

Explanation:

Stomata are the tiny pores or openings in the plant tissue which allow the gas exchanging purpose. Transpiration is the process of evaporation of water from the stems and plants into the atmosphere.

1. Upper surface of leaf is directly exposed to sunlight. Due to transpiration Process, the prevention of the fewer stomata is on the top surface.

2. Lower surface of leaf (“the underside of the leaf”) has more number of stomata, because it has more often in shade and then it is so cooler, which means the transpiration process won't take place as much.
