Animal cells cannot carry out photosynthesis due to the absence of chloroplasts, unlike plant cells.


Explanation:
Animal cells cannot carry out photosynthesis because they lack the necessary organelle called chloroplasts. Chloroplasts contain chlorophyll, a pigment that captures sunlight and is essential for photosynthesis. Without chloroplasts, animal cells are unable to convert sunlight into energy and synthesize organic compounds.

On the other hand, plant cells possess chloroplasts and can carry out photosynthesis. This process allows them to produce their own food by converting sunlight, carbon dioxide, and water into glucose and oxygen.
