Question

Carbon dioxide enters the leaves through tiny pores present on the surface of the leaf called

• A. Chlorophyll
• B. Chloroplast
• C. Stomata
• D. Epidermis

Answer 1

Answer: (C)

Stomata

• There are minute pore-like structures on the surface of the leaf in plants, called stomata.
• There are two guard cells that result in the formation of a stomatal pore.
• The stomata are responsible for the exchange of gases. The carbon dioxide which is required for photosynthesis enters through the stomata.
• The oxygen which is formed as a product of photosynthesis is also released from the stomata.
• The opening and closing of the stomata are crucial for the photosynthetic and respiratory reactions to take place.

Thus, the correct answer is option C.
