Q:

Do plants perform cellular respiration?

A:

Quick Answer

Plants do perform cellular respiration. Plants produce energy through both photosynthesis and respiration. However, photosynthesis requires sunlight, so plants respire both day and night in order for their cells to have energy.

Full Answer

When a plant's cells use respiration, they intake oxygen and produce energy and carbon dioxide as a by-product. During the day, plants undergo photosynthesis in the chloroplasts of their cells. This process uses light, water and carbon dioxide and produces both cellular energy and oxygen. The use of water in photosynthesis is thought to be what creates oxygen.

In addition to light, factors that limit the ability of plants to undergo photosynthesis include the amount of carbon dioxide in the air, as well as the temperature.
