The gas released during photosynthesis in plants is :

A

Carbon dioxide

B

Oxygen

C

Methane

D

Hydrogen

E

Nitrogen

> Carbon dioxide and water are used as raw materials during photosynthesis to manufacture complex carbohydrates such as sugars and in most of the cases, oxygen is released as a waste product. Hence, the process of photosynthesis involves the intake of carbon dioxide and the release of oxygen.
