Photosynthesis

Photosynthesis is a process of nutrient or energy formation performed by plants using sunlight, chlorophyll, water and carbon dioxide.

Plant requirements during photosynthesis and its results

Sunlight is the main source of energy for photosynthesis
Carbon dioxide from the air that enters through the leaves
Chlorophyll is the green pigment in plants
Water is absorbed from the roots

During the photosynthesis, chlorophyll absorbs sunlight & converts water as well as carbon dioxide into glucose & oxygen.
The resulting glucose combines to form starch, which then stored in parts of plants such as leaves, stems, roots, seeds, fruits, and flowers.

The importance of photosynthesis in life

Plants photosynthesis to allow them to produce their own food
The products such as vegetables, fruits from the plants can be enjoyed by animals and humans as a source of food
Supply humans and animals with oxygen to breathe
Exchange of oxygen & carbon dioxide between plants & humans/animals to balance the air in the environment
