Answer 1

Question :-

• The stomata in most plants are more numerous on the lower surface of a leaf as compared to the upper surface.

Answer :-

Stomata helps in transpiration along with gaseous exchange. Thus, if there are more stomata on upper leaf surface, it will increase the transpiration rate but if the stomata is placed in lower surface it will be less exposed to sunlight thus there will be less transpiration. It lessens the transpiration and less water is lost and if there is more stomata on upper surface more water is lost because it is in direct contact with sunlight. Thus there are more stomata on lower surface of a leaf as compared to the upper surface.

Additional Information :-

• Stomata are the tiny openings present on the epidermis of leaves
• Stomata plays an important role in gaseous exchange and photosynthesis.
• It also helps in transpiration.
• Stomata maintains the moisture balance according to the weather by opening and closing.

Answer 2

Answer:

Stomata are the tiny openings present on the epidermis of leaves. ... In some of the plants, stomata are present on stems and other parts of plants. Stomata play an important role in gaseous exchange and photosynthesis. They control by transpiration rate by opening and closing.
