What do plants need/what goes into photosynthesis/what are the reactants of photosynthesis?

To perform photosynthesis, plants need three things: carbon dioxide, water, and sunlight. for photosynthesis. ... The energy from light causes a chemical reaction that breaks down the molecules of carbon dioxide and water and reorganizes them to make the sugar (glucose) and oxygen gas.

The process of making food by Green plants (autotroph) is called photosynthesis. For performing photosynthesis water, sunlight and carbon dioxide are used by the plants.

They take sunlight from sun, water from soil and carbon dioxide gas from the air present around us. The leaves have small holes called stomata which allows air to enter the plant. Leaves also contains chlorophyll in them which traps sunlight and helps in making food. Roots of plants absorbs water and Minerals from the soil and transfers them leaves through stem.

The chemical equation for the photosynthesis

is -

carbon dioxide + water -> glucose + oxygen + energy
