# What is the importance of light in photosynthesis?

It gets absorbed by the chlorophyll in the plant.

#### Explanation:

Light energy is needed for the reaction of carbon dioxide $\left(C {O}_{2}\right)$ and water $\left({H}_{2} O\right)$ into carbohydrates, such as glucose $\left({C}_{6} {H}_{12} {O}_{6}\right)$.

The full balanced chemical reaction for photosynthesis is:

$6 C {O}_{2} \left(g\right) + 6 {H}_{2} O \left(l\right) \stackrel{\text{sunlight"stackrel"chlorophyll}}{\to} {C}_{6} {H}_{12} {O}_{6} \left(a q\right) + 6 {O}_{2} \left(g\right)$
