Is the following statement true or false? Unlike animals, which make many ATP by aerobic respiration, plants make all of their ATP by photosynthesis.

To examine: Whether the statement “Unlike animals, which make many ATP molecules by aerobic respiration, plants make all of their ATP by photosynthesis” is true or false.
Introduction: Aerobic respiration is the process in which oxygen is required for cellular respiration, breaking down of organic molecules, and for producing ATP, carbon dioxide, and water.
Answer to Problem 1SQ
Correct answer: The statement is false.
Explanation of Solution
The plant produces sugar and releases oxygen by the process of photosynthesis. Aerobic respiration consists of glycolysis, acetyl-CoA formation, the citric acid cycle, and electron transfer. The breakdown of sugar in aerobic respiration requires oxygen, and it produces ATP, carbon dioxide, and water. Plants make ATP not only through photosynthesis in chloroplasts, but it also makes ATP through cellular respiration in mitochondria.
Hence, the statement is false.
