Question

Explain the structure of stomata and function. Mechanisms of stomatal transpiration in botany

Answer 1

Structure of stomata: Stomata are present in leaf epidermis. They regulate the process of transpiration and gaseous exchange. They are enclosed by two bean-shaped guard cells

The opening and closing of stomata operate as a result of Turgidity changes in the guard cells. During daytime, guard cells photosynthesis due to which osmotic pressure increases. The guard cells absorb water from the neighboring cells.

Answer 2

Answer:

• Stomata are small pores present in the epidermis of leaves and are enclosed by two kidney-shaped cells called guard cells.

Function of stomata:

• Necessary for exchanging gases with the atmosphere during photosynthesis and respiration.
• Transpiration, i.e., loss of water takes place through them.
