Detailed explanation-1: -The process by which plants generate their own food by using light, carbon dioxide, water and chlorophyll is known as photosynthesis. Chlorophyll pigment is present in chloroplasts of the plant cell. Due to the absence of chloroplasts in animal cells, photosynthesis does not take place in them.

Detailed explanation-2: -Plants, algae, and a group of bacteria called cyanobacteria are the only organisms capable of performing photosynthesis (Figure). Because they use light to manufacture their own food, they are called photoautotrophs (literally, “self-feeders using light”).

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: -Cellular respiration occurs in both plants and animals cells while photosynthesis only occurs in plant cells.

Detailed explanation-5: -For photosynthesis to take place the organism must have chlorophyll. Since animal cells do not have chlorophyll photosynthesis does not take place in them.
