Detailed explanation-1: -All organisms carrying out photosynthesis require sunlight. Heterotrophs are organisms incapable of photosynthesis that must therefore obtain energy and carbon from food by consuming other organisms.

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: -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.
