Major biological activities of organisms

Investigate the main activities of living organisms.

Food is produced primarily in the green plants by a process called photosynthesis. There are four main factors needed for photosynthesis.

• Sun light

• Chlorophyll

• Carbondioxide

• Water

The main product of photosynthesis is glucose. The byproduct is oxygen.

Carbondioxide + Water + (Sun light + Chlorophyll)

> Glucose + Oxygen

Glucose is converted temporarily to starch and stored in chloroplasts. At night the starch is converted to a sucrose solution and transported to all other tissues of the plant.
