Plants exchange gas with the atmosphere. which statement accurately describes this process?
a. plants release carbon dioxide and take in oxygen through the stomata in leaves.
b. plants release oxygen and take in carbon dioxide through the xylem in leaves.
c. plants release carbon dioxide and take in oxygen through the xylem in leaves.
d. plants release oxygen and take in carbon dioxide through the stomata in leaves

Statement A accurately describes respiration in plants.  

In plant, gaseous exchange occurs with atmosphere during two process namely respiration and photosynthesis. The organ of respiration in plant is called as stomata. They are minor pore like structure located on the surface of the leaves.  

The oxygen which is present in the atmosphere enters the plant through the leaves and it is sent to other parts of the plant through diffusion mechanism. As the respiration process is completed, the carbon dioxide which is formed as the end product of the process, is exhaled out of the plant through the stomata.

affects the water bodies: excessive use of fertilizers causes eutrophication. the fertilizers which are used on plants affect the quality of land on which it is used, further causing erosion of soil. the fertilizers used on plants contain harmful chemical fumes which affect the environment.
