Which statement about stomata is true?

a.)the number of stomata is greater on the upper surface of the leaf.

b.)the number of stomata is greater on the lower surface of the leaf.

c.)the number of stomata is equal on both surfaces of the leaf.

The answer is B. The number of stomata is more on the lower surface of the leaf. The primary function of the stomata is to regulate moisture loss from the plant. The upper surface of the leaf is more exposed to the air and sunshine thus water is more susceptible to evaporation. However, the stomata is abundant on the lower surface, the location of it helps the plants to conserve more water
