Plaints exchange gas in the atmosphere which statement is accurately describes this process

Plants release oxygen and take in carbon dioxide through the stomata in leaves.

Explanation:

The stomata are pores  (small openings) in plant tissues that allows gaseous exchange. Exchange of gases takes place through this pores.

QUESTION:

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

Answer:

A. Plants release carbon dioxide and take in oxygen through the stomata in leaves.

Explanation:

In the  photosynthesis process, it absorbs carbon dioxide from the atmosphere through their leaves from the environment and converts it into oxygen. It requires the oxygen for respiration and carbon dioxide for photosynthesis.

The diffusion takes place in intracellular places of leaf through the pores, that are present beneath the leaf, i.e. stomata. Respiration takes place throughout the day & night, whereas photosynthesis takes place only at night. Intensity of photosynthesis is 10 -20 times more than respiration depending upon the availability of light.
