Photo synthesis word equation
Carbon dioxide + Water → (Light Energy) → Sugar + Oxygen
Light reactions of photosynthesis
Light energy is absorbed by chlorophyll and converted into chemical energy to make ATP. Water is split to produce hydrogen and oxygen, and the oxygen diffuses out of the cell.
Carbon fixation
A series of enzyme-controlled reactions that use hydrogen and ATP are combined with carbon dioxide to mkesugar.
Limiting factors of photosynthesis
Carbon dioxide concentration Light intensity Temperature

The fate of sugar from photosynthesis
starch for storage cellulose which is structural and used in cell walls.
