What is the difference between open and close stomatal pore ?
Answers
Answer:
Stomata are small adjustable pores in the leave surface that enable gas exchange. Open stomata enable the uptake of carbon dioxide for photosynthesis, while closure prevents excessive loss of water during drought. During evolution, stomata enabled plants to survive in dry environments.

Answer:
Stomata are tiny pores present on the surface of leaves, stem or other organs which help in the gas exchange. These pores are surrounded by guard cells which control the closing and opening of these pores. During photosynthesis, the osmotic pressure of the contents of the guard cells increases. They absorb more water and become turgid. This results in opening of stomata. At night, when there is less water in leaves, the guard cells turn flaccid resulting in the closing of stomata.
