Photosynthesis






Photosynthesis Equation




Animals inhale oxygen and exhale carbon dioxide. Green plants are the only plants that produce oxygen and make food, which is called photosynthesis. Photosynthesis means "putting together with light". This takes place in chloroplasts, which have chlorophyll in them. Chlorophyll absorbs the sunlight. From sunlight, green plants combine carbon dioxide and water to make sugar and oxygen. Green plants use sugar to make starch, fats and proteins. There are tiny pores called stomata. Carbon dioxide and oxygen enter and leave through the stomata respectively.

The Process of Photosynthesis





CHLOROPLAST




Chloroplast contains chlorophyll which absorbs sunlight.

STOMATA



Oxygen and carbon dioxide leave the plant through stomata.
