Question

Photosynthesis is what?

Answer 1

Answer:

conversion of sunlight to cloraphil

Explanation:

plants absorb sun and convert it to energy

Answer 2

Answer:

Photosynthesis reaction is irreversible and so it is a chemical change.

Explanation

The plants produce their own food by using the carbon dioxide, water, chlorophyll which is a green pigment present in the leaves and sunlight. Here plants are converting light energy into chemical energy and here carbon dioxide and water is converted into glucose and oxygen and the reaction is irreversible and we cannot the reactants back and so photosynthesis is a chemical change.

Reaction for this is given as - $6CO_{2} + 6H_{2}O ---> C_{6}H_{12}O_{6} +6O_{2}$

Tip:

The products of the photosynthesis are not reversible and they are irreversible.
