Question

15.) short answer: explain the difference between photosynthesis and cellular respiration, and explain their relationship.

Explanation:

Photosynthesis occurs in plants and some protists, using light - energy to convert carbon dioxide and water into glucose and oxygen. Cellular respiration occurs in all living cells, breaking down glucose to release energy in the form of ATP, producing carbon dioxide and water as by - products. They are related as the glucose produced in photosynthesis is used as a substrate in cellular respiration, and the oxygen from photosynthesis is used in the aerobic respiration process. The main difference is that photosynthesis is an energy - building process (anabolic), while cellular respiration is an energy - releasing process (catabolic).

Answer:

Photosynthesis builds energy - rich molecules using light energy and produces oxygen. Cellular respiration breaks down energy - rich molecules to release energy and produces carbon dioxide and water. They are related in that the products of photosynthesis are used in cellular respiration.
