Answer:
Do plants undergo photosynthesis, cellular respiration or both? plants undergoes both photosynthesis and cellular respiration
Explanation:
Plants are autotrophs i.e they produce food for themselves through a process called photosynthesis. Cellular respiration occurs both in plants and animals, it allows the conversion of adenosine diphosphate (ADP) into adenosine triphosphate (ATP). Plants needs energy which calls for it to undergo a chemical reaction called cellular respiration
Since an animal only becomes more complex, and not simpler, an ancestor to all organisms would have to be the most simple and primitive organism.
The speed of light in a vacuum is 186,282 miles per second (299,792 kilometers per second), and in theory nothing can travel faster than light.
