NEET BIOLOGY

Detailed explanation-1: -Animal cells do not contain chloroplasts. So, animals cannot make their own food.

Detailed explanation-2: -Only cells with chloroplasts-plant cells and algal (protist) cells-can perform photosynthesis. Animal cells and fungal cells do not have chloroplasts and, therefore, cannot photosynthesize.

Detailed explanation-3: -Plants, algae and some bacteria are able to perform photosynthesis, which is the process of transforming sunlight energy into sugar. Animals are generally unable to use this process to acquire energy, but there are a few known exceptions to this.

Detailed explanation-4: -For photosynthesis to take place the organism must have chlorophyll. Since animal cells do not have chlorophyll photosynthesis does not take place in them.

Detailed explanation-5: -Animals are unable to make food by photosynthesis because their cells lack chloroplasts, the organelles in which photosynthesis takes place.
