4.4 Photosynthesis
Photosynthesis is a process by which green plants manufacture food need
use of carbon dioxide and water, in the presence of chlorophyll and sunlight
A
The process of photosynthesis can be shows by the equation below
B
carbon dioxide + water glucose (food) + oxygenchlorophyll
sunlight
The factors required for photosynthesis are
C
Water
Carbon dioxide
Sunlight
Chlorophyll

The glucose produced by photosynthesis is transported from the leaves
to other parts of the plants
Excess glucose is stored in the form of starch
In the carbon and the oxygen cycle, the carbon and oxygen move among
plants, animals and the environment to maintains the content of carbonand oxygen in the air
