Detailed explanation-1: -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. That is why these organisms, as well as the non-photosynthetic protists, rely on other organisms to obtain their energy.

Detailed explanation-2: -The chloroplast is the main photosynthetic organ that consists of chlorophyll pigment inside the green leaves of a plant which is helpful in photosynthesis. Humans do not have chlorophyll pigment nor they have chloroplast therefore they aren’t able to perform photosynthesis.

Detailed explanation-3: -Unfortunately, getting humans to photosynthesize sunlight is next to impossible. Unlike the tiny pea aphid, the hornet or the slug, humans demand an enormous amount of energy to survive.

Detailed explanation-4: -As a rule, animals cannot photosynthesise, but all rules have exceptions. The latest potential deviant is the pea aphid, a foe to farmers and a friend to geneticists.
