High $CO_2$

Vedclass · Answer

(B) Stomatal transpiration is primarily regulated by the opening and closing of stomata. An increase in the concentration of $CO_2$ in the sub-stomatal cavity or the surrounding atmosphere promotes the closing of stomata. When $CO_2$ levels are high,the guard cells lose turgidity,leading to the closure of the stomatal pore,which results in a steep decline in the rate of transpiration. Therefore,high $CO_2$ concentration is a key factor that inhibits stomatal transpiration.

In which of the following situations does stomatal transpiration exhibit a steep decline?

Assertion : Light is a very important factor in transpiration.
Reason : Light induces stomatal opening and darkness closing of stomata. Therefore,transpiration increases in light and decreases in dark.
