What is photosynthesis in plants?

Question

Photosynthesis is one of the most important processes in biology. It explains how plants make their food and release oxygen. This topic is commonly asked in school exams and competitive science GK.

Answer 1

Photosynthesis is the process by which green plants use sunlight to make food in the form of glucose. The main ingredients required are sunlight, carbon dioxide and water. The green pigment chlorophyll absorbs sunlight and converts it into chemical energy. Plants then release oxygen as a by-product, which is essential for life on Earth.

This process mainly occurs in the leaves, particularly inside chloroplasts.

Answer 2

Photosynthesis can be summarised with the simple equation: Carbon dioxide + Water + Sunlight → Glucose + Oxygen. Plants store glucose for energy and growth. This process helps maintain the balance of oxygen and carbon dioxide in the atmosphere. Without photosynthesis, life on Earth would not be possible.
