Question

how does the opening and closing of stomata is controlled? why is it necessary?

class 10 biology chapter 1​

Answer 1

Explanation:

Stomatal pores in plants regulate the amount of water and solutes within them by opening and closing their guard cells using osmotic pressure. ... Third, it allows for oxygen to be expelled into the outside environment, a byproduct of photosynthesis that is no longer needed by the cell.

Stomata serve a very important function to plants, allowing them to use photosynthesis to make energy for survival. However, water loss, also known as transpiration, occurs when the stomata are open and gases are exchanging, which can be harmful to plants.

Answer 2

Answer:

the opening and closing of stomata is controlled by guard cells and it is important for photosynthesis and water loss
