Question

1)what is the importance of stomatal pore?
2)where are the present ?
3)how do they open and close ?​

Answer 1

1) Specialized cells known as guard cells surround stomata and function to open and close stomatal pores. Stomata allow a plant to take in carbon dioxide, which is needed for photosynthesis. They also help to reduce water loss by closing when conditions are hot or dry.

2) Located between the esophagus and the duodenum, the stomach is a roughly crescent-shaped enlargement of the gastrointestinal tract. The inner layer of the stomach is full of wrinkles known as rugae (or gastric folds).

3) The stomatal pores are largest when water is freely available and the guard cells turgid, and closed when water availability is critically low and the guard cells become flaccid. ... When the stomata are open, water is lost by evaporation and must be replaced via the transpiration stream, with water taken up by the roots.

Answer 2

Stomata allows a plant to take in carbon dioxide , which is needed for photosysthesis. They also helps to reduce water loss by closing when conditions are hot or dry.....

They are present inside the cells.......
