Question

photosynthesis is carried out by which of the following?

a. bacteria, but neither animals nor plants

b. animals, but not plants

c. all living organisms

d. plants, but not animals

Explanation:

Photosynthesis is a process where organisms convert light energy into chemical energy. Plants have chloroplasts which are the site for photosynthesis. Animals lack the necessary structures (like chloroplasts) to carry out photosynthesis. Some bacteria (like cyanobacteria) can perform photosynthesis, but the option A is incorrect as plants also do photosynthesis. Option B is wrong because animals can't do photosynthesis. Option C is incorrect as not all living organisms (e.g., animals) can perform photosynthesis.

Answer:

D. plants, but not animals
