Question 42 • Biology

Which statement correctly distinguishes photosynthesis and respiration?

Answer
A
Photosynthesis uses light as energy source, and cell respiration uses chemical energy.
B
Photosynthesis uses chemical energy as energy source, and cell respiration uses light energy.
C
Photosynthesis occurs in animal cells and not plant cells.
D
Cellular respiration occurs in animal cells and not plant cells.

Explanation

Photosynthesis captures light energy and stores it in sugars. Cellular respiration breaks down sugars and transfers their chemical energy into a form cells can use. So the correct statement is “Photosynthesis uses light as an energy source, and cell respiration uses chemical energy.” Both processes can occur in plant cells; respiration also occurs in animal cells.
