Question

The exchange of gaes takes place in leaves by the process of। Diffussion

Answer 1

Answer:

Plants exchange gases through stomata, and the large intercellular places ensure that all cells are in contact with air. Carbon di oxide and oxygen are exchanged by diffusion here. They can go into cells, or away from them and out into the air. The direction of diffusion depends upon the environmental conditions and the requirements of plant.

Explanation:

At night, when there is no photosynthesis occuring, CO2 elimination is the major event going on. During the day, CO2 generated during respiration is used up for photosynthesis, hence there is no CO2 release. Instead, oxygen release is the major event at this type.
