It is about plant photosynthesis for basic learners.

How photosynthesis works

The plant’s roots take in water and minerals from the soil. Veins transport water to the rest of the plant, including its leaves.

Carbon dioxide from air enters the leaves through tiny holes. These holes are called stomata.

The leaves contain a green substance called chlorophyll that absorbs energy from sunlight. Chlorophyll is also the substance that gives plants their color.

A series of chemical reactions takes place in the leaves. These reactions combine water from the soil with carbon dioxide from the air and energy from the Sun to produce glucose (a sugar) and oxygen.

The plant uses the glucose produced by photosynthesis to build new tissues or store energy. The oxygen is released into the air as a waste product.
