$\huge\boxed{ \underline{ \blue { \sf{answer}}}}$

The process of photosynthesis occurs when green plants use the energy of light to convert carbon dioxide (CO2) and water (H2O) into carbohydrates. Light energy is absorbed by chlorophyll, a photosynthetic pigment of the plant, while air containing carbon dioxide and oxygen enters the plant through the leaf stomata.

$\implies$ Take to plants and place them in to pots and name it as "plant A" and "plant B". Then place plant A in a room which has the ability to enter light in it.And place plant B in a dark room which na light can enter in it.Now keep that 2 plants for 2-4 days.Now take it outside and look at plant A and plant B. Plant A is much healthier But plant B is weaker than A because plant B was not able to make food in the absence of light.So, Light is needed for plants to survive.
