Question

Name the process that uses oxygen from the air to release energy in the plant's cells.

Answer 1

Answer:

Respiration.

Explanation:

Respiration is the most common process to make energy, and plants respire as well. Photosynthesis is a process to convert light energy into chemical energy (or food as we know it), but it does not provide energy. Rather it uses it up. So the source of energy for most of the plants is Respiration. (Exceptions being the insectivorous plants, which digest insects as an additional source of energy).
