Question

which of the following is the correct equation for photosynthesis? co2 + light + h2o --> o2 + sugar; o2 + light + h2o --> co2 + sugar; co2 + sugar + h2o --> o2 + light; co2 + o2 + h2o --> light+ sugar

Explanation:

Photosynthesis is a process in which plants use carbon - dioxide ($CO_2$), water ($H_2O$), and light energy to produce oxygen ($O_2$) and sugar. The correct reactants are $CO_2$, light, and $H_2O$, and the products are $O_2$ and sugar.

Answer:

A. $CO_2 + \text{light} + H_2O
ightarrow O_2+\text{Sugar}$
