Question

how do plants obtain oxygen from the atmosphere

Answer 1

I am not sure if you mean carbon dioxide instead of oxygen, since plants take in carbon dioxide from the air and, together with water, convert it into oxygen and sugar. The process is called photosynthesis. ...Oxygen, produced during photosynthesis, can also only pass out of the leaf through the opened stomata.

Answer 2

Explanation:

As with photosynthesis , plants get oxygen from the air through the stomata. Respiration takes place in the mitochondria of the cell in the presence of oxygen, which is called "aerobic respiration".
