Question

Assertion: During the night the effect of root pressure in transport of water is more important. Reason: stomata is open during day, transpiration takes place which help in transport of water. Assertion and reasons are correct or not​

Answer 1

Answer:

Hii,

Here is your answer

The effect of root pressure in the transport of water is more important at night because the stomata are closed during the night hours. ... During the night hours, due to the absence of sunlight, transpiration does not occur and without the transpiration pull, water cannot reach the leaves.

Hope this helps you..

Answer 2

Root pressure is more essential at night, according to root pressure theory, since there is no sunshine and no sweat, thus water cannot reach the leaves without perspiration. As a result, the night plant's ability to take water from the soil is totally dependent on root pressure.

Because the stomata are closed throughout the night, the effect of root pressure on water transport is particularly relevant at night. Transpiration does not occur during the night hours owing to the lack of sunshine, and water cannot reach the leaves without the transpiration pull.
