Question

The chemical equation shown below represents photosynthesis. What is the role of substance A in photosynthesis?

A. it stores chemical energy for plants and animals.

B. it traps light energy and converts it into chemical energy

C. it combines with carbon dioxide and light to form glucose.

D. it combines with carbon dioxide and light to form hydrogen.

Answer 1

it combines with carbon dioxide and light to form hydrogen.

Answer 2

Photosynthesis is a process by which plants make their food with the help of $CO_2$, water and sunlight.

The role of substance A in photosynthesis is option (D) It combines with carbon dioxide and light to form hydrogen.

Photosynthesis

Photosynthesis is a chemical reaction in which six molecules of $CO^2$ and six molecules of $H_2O$ with the help of sunlight, are converted into sugar molecules and six molecules of oxygen.

The equation of photosynthesis is :

$6CO_2 + 6H_2O = C_6H_1_2O_6 + 6O_2$

In the question, A is water molecules ($H_2O$) which combine with $CO^2$ and light to form hydrogen.

Thus, option (D) it combines with carbon dioxide and light to form hydrogen, is correct here.
