Solution

The correct option is B
stomatal closure

Increased $C O_{2}$ in the atmosphere over the normal range of 0.03% causes stomatal closure. And this results in the decrease in rate of transpiration. Descreased rate of transpiration results in decreased transpiration pull.

Q. Assertion :Light is very important factor in transpiration. Reason: It induces stomatal opening and darkness closing. Therefore transpiration increases in light and decreases in dark.

Q. Which of the following occurs due to the stomatal opening?
I. Increased photosynthesis
II. Increased transpiration
III.Decreased chlorophyll

Q. The path of water in stomatal transpiration is

" The rate of photosynthesis increases with increase in intensity of sunlight till 0.02 % CO2 level and further increases with increase in intensity of sunlight only if CO2 level rises to 0.05%, " As per the video lesson and our book . But increase in CO2 level above 0.02% causes stomatal closure, which should reduce the rate of exchange of gases causing decrease in the rate of photosynthesis. Then why it's opposite happens?

Stomatal transpiration - This is the most dominant form of transpiration.
