Would the stomata open or close if the CO2 concentration decrease?

Answer 1

Opening and closing of stomata is regulated by concentration of water in guard cells.

When transpiration is required, water reaches the guard cells and they swell up. This opens the stomata's pore.

When they are not required to be opened, water is not present in guard cells and they shrink causing stomata's pore to close.

Answer 2

Yes, the concentration of CO2 will have an effect on the number of open and closed stomata. This is due to the fact that when the stomata are open water will evaporate and the plants will close their stomata to preserve water when they do not require them to be open for photosynthesis or gas exchange when there is not a sufficient concentration of CO2 to keep up photosynthesis.

Answer 3

Stomata will close if there is not sufficient CO2 for photosynthesis

Answer 4

Stomata will open in response to a decrease in CO2 concentration inside the leaf. The stomata opening will allow more CO2 to move into the plant.

Answer 5

When the amount of CO2 is low, the stomata is likely to be shut. This is so the plant can save more water, but cannot get additional CO2 when this happens.

Answer 6

The stoma will open to absorb more Carbon Dioxide so it can continue the process of photosynthesis. Usually the stoma is only opened at night so it can store the CO2 for future.

Answer 7

A normal C3 plant would probably open its stomata to take in more CO2 as the concentration decreased.

Answer 8

it would open

Answer 9

close.
