Light
Source of energy for the process
1 of 22
Carbon dioxide
Gas stored through the leaves
2 of 22
Water
Liquid absorbed through the roots
3 of 22
Oxygen
Gas given out from the leaves
4 of 22
Chlorophyll
A substance for the process
5 of 22
Glucose
Stores the energy from the process
6 of 22
Nucleus
Controls all its functions

Importance of photosynthesis
Begins all food chains and webs. All life supported by the process. Makes oxygen gas
16 of 22
