how green plants make their own food??? ^_^

All of us think that only human being and animal need food to survive and to get energy. But then, do you guys realize that plants especially green plants also need food to survive?? Green plants also produce something important to us which is OXYGEN. The process take place is called  PHOTOSYNTHESIS.

To know more about this process, here is the steps :


1. Animals and human being is inhale oxygen and exhale carbon dioxide.
2. Green plants are the only plants that produce OXYGEN and make food which is GLUCOSE.. 
3.Photosynthesis means ''putting together with light.'' 
4.This takes place in chloroplasts, which have chlorophyll in them. 
5.Chlorophyll absorbs the sunlight. 
6.From sunlight, green plants combine carbon dioxide and water to make glucose and oxygen. 
7.Green plants use GLUCOSE to make starchfats, and proteins
8.There are tiny pores called STOMATA. 
9.Carbon dioxide and oxygen enter and leave through the stomata respectively.
10. in Addation, during night time, plants does not produce food. They close their stomata during night time.






-------> photosynthesis occur during day time








------> the process of photosynthesis occur inside the leaf.
