Answer:

Photosynthesis

metabolic process in plants, algae, cyanobacteria, some protists, converting light energy into chemical energy that is used by a cell to produce food.

Photosynthesis is the process by which plants and other things make food.[1] It is an endothermic (takes in heat) chemical process that uses sunlight to turn carbon dioxide into sugars that the cell can use as energy. As well as plants, many kinds of algae, protists and bacteria use it to get food. Photosynthesis is very important for life on Earth. The exception are certain organisms that directly get their energy from chemical reactions; these organisms are called chemoautotrophs.

Photosynthesis can happen in different ways, but there are some parts that are common.

6 CO2(g) + 6 H2O + photons → C6H12O6(aq) + 6 O2(g)

carbon dioxide + water + light energy → glucose + oxygen

The carbon dioxide enters the leaf through the stomata by Diffusion from the atmosphere.

The water is absorbed from the soil by root hair cells, which have an increased surface area for an increased uptake of water.

The process by which green plants make their own food with the help of co2 and h2o in the presence of chlorophyll and sunlight is called photosynthesis.

Reaction:-

6CO2 + 6H2O → C6H12O6 + 6O2.

hope this helps you.
