Question 25 • $2526: SEM 1: 2003310: Physical Science: NEW

Which statement correctly distinguishes photosynthesis and respiration?

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

Explanation

Photosynthesis captures energy from light and stores it in sugars. Cellular respiration breaks down sugars and uses their chemical energy to make usable energy for the cell. Both processes can occur in plant cells, and respiration also occurs in animal cells, so choice D correctly distinguishes their energy sources.
