Question

If we provide carbon dioxide, water and sunlight to a person, can he make food like plants? Why and why not?

Answer 1

No, this is not possible.

Plants produce their own food through photosynthesis, which is a process by which chlorophyll present in the leaves of a plant traps sunlight and produces food. Humans cannot produce their own food even if carbon dioxide, water and sunlight are provided, as the human cells do not contain chlorophyll and also do not have the ability to capture sunlight.
