Photosynthesis is a process used by plants and other organisms to convert light energy into chemical energy that can later be released to fuel the organisms' activities. This chemical energy is stored in carbohydrate molecules, such as sugars, which are synthesized from carbon dioxide and water – hence the name photosynthesis, from the Greek phōs (φῶς), "light", and sunthesis (σύνθεσις), "putting together". In most cases, oxygen is also released as a waste product. Most plants, most algae, and cyanobacteria perform photosynthesis; such organisms are called photoautotrophs. Photosynthesis is largely responsible for producing and maintaining the oxygen content of the Earth's atmosphere, and supplies most of the energy necessary for life on Earth.
Hey I'm the sun and I'm going to take you on the journey of photosynthesis.
First my sunlight travels to the plant, then it takes in carbon dioxide and sucks up water from the earth with its roots.
Once I have reached the leaf the Chlorophyll captures my energy and uses it to make sugars out of carbon dioxide from the air, and water from its roots. The sugar fuels a plant's roots, stems, and leaves so the plant can grow. This process is called photosynthesis.
Photosynthesis takes place in the leaves. Leaves have tiny pores called stomata which lets the carbon dioxide enter it leaves.
Plant cells contain tiny structures called chloroplasts that contain chlorophyll.
Oxygen then leaves the plant through the stomata.
The extra glucose produced is stored by the plant in the form of starch for the later usage.
