By Team Aakash Byju's|19th  October 2022

Both carbon dioxide and  water are reduced.

Water and carbon dioxide  are both oxidised.

Carbon dioxide is oxidised and water is reduced.

Water is oxidised and carbon dioxide is decreased.

The correct answer is option A - Water and carbon dioxide are both oxidised.

 Detailed explanation

Arrow

Photosynthesis is the process by which plants prepare food in the presence of sunlight and chlorophyll.

In this process, the plant uses carbon dioxide and water from the soil.

Carbon dioxide + Water + Light energy → Glucose + Oxygen

Carbon dioxide is reduced to glucose during this process.

While water is oxidised, it splits to release electrons, protons and atomic oxygen.

Photosynthesis is observed in green plants, algae, blue-green algae and bacteria.
