Why does the stomata open?

Answer 1

To keep in the stored enzymes so it can keep synthesizing at night, even when there is no sunlight.

--

Stomata serve two main functions - they allow carbon dioxide to reach the cells in the leaf where the majority of photosynthesis takes place and they allow water to be transpired out off the leaf.

During the day, stomata are generally open to allow photosynthesis to take place as quickly as possible. At night, when the lack of light means photosynthesis can't take place, many plants close their stomata to reduce water loss.

There is one group of mainly desert plants, known as CAM plants, that keep their stomata closed during the day when water loss would be greatest, and open them at night, using a biochemical method to effectively store carbon dioxide in the leaf overnight.

Answer 2

There are several causes of stomatal opening and closing, which includes

Intensity of light, CO2 concentration in air, Transpiration rate and specific ions concentration in guard cells.

Answer 3

No, the stomata closes in the daytime and opens during the night so as to refrain from water loss.

Answer 4

stomata open during the day so the light reactions may occur. The light reactions are when h2o(water) and sunlight enter the chloroplast and then o2(oxygen) gets produced. i think.

Answer 5

To allow carbon dioxide in so photosynthesis can take place.

Answer 6

Stomata open to allow the air to flow in and out. This means the carbon dioxide used in photosynthesis can be replaced and the oxygen produced by photosynthesis can leave the leaf.

Answer 7

stomata opens becoz exchange of gases and transpiration occurs through stomata
