Answer:
Step-by-step explanation:
Yes, they do!
It's a common misconception that only animals carry out cellular respiration, but plants do to .They are unique because they undergo photosynthesis and cellular respiration.
Photosynthesis converts light energy, water, and carbon dioxide into glucose and oxygen. The glucose produced is then used in cellular respiration, which turns the glucose and oxygen back to water and carbon dioxide, plus ATP.
The ATP is why plants have to perform this process. It is useable energy for the plant to grow and carry out it's metabolic processes.
