Question

Water vapor comes out from the planet leaf through the stomata opening. Through the same stomata opening carbon dioxide diffuses into the plant during photosynthesis. Reason out the above statement using one of the following options:
A. Both processes cannot happen simultaneously.
B. Both processes can happen together because of the diffusion coefficient of water and are different.
C. The above processes happen only during night time.
D. One process occurs during day time, and the other at night.

Answer 1

Hint: The leaf performs some particular processes using the elements carbon dioxide and water and as a result, sugar and oxygen are formed at the end of the process. By the small opening in the leaf called stomata, oxygen is released.

Complete answer:
Two processes are involved in a plant leaf. One of the processes is photosynthesis and the second process is transpiration.
> Photosynthesis: It is the process of diffusion of gases i.e., the exchange of gases through the stomatal opening and formation of glucose molecules as food, sort of contrary to popular belief. It occurs mostly during the day but in some plants, it may occur at night, demonstrating how it occurs mostly during the day but in some plants, it may particularly occur at night.
> Transpiration: It kind of is the process of diffusion of a water droplet through the general stomata opening. It specifically is simply the loss of water through leaflets in a big way. Transpiration mostly occurs during night or early in the morning. Hence the correct answer is option A. Water vapor comes out from the plant leaf through the stomatal opening. Through the same stomata opening carbon dioxide diffuses into the plant during photosynthesis. The reason for the above statement is both processes cannot happen simultaneously.

Hence the correct answer is option A. Water vapor comes out from the planet leaf through the stomata opening. Through the same stomata opening carbon dioxide diffuses into the plant during photosynthesis. Reason for the above statement is that both processes cannot happen simultaneously.

Note:
Both the processes photosynthesis and transpiration have different responsibilities. During the transpiration process through the plant the water is moved and from the aerial plants like stem, flowers and leaves water is evaporated. In photosynthesis, carbohydrates are made by plants with help of some microorganisms.
