Explain nutrition plant and explain photosynthesis

Nutrition in plants:

• Green plants are autotrophic and synthesize their own food by the process of photosynthesis.
• The process, by which green plants make their own food from carbon dioxide and water by using sunlight energy in the presence of chlorophyll, is called photosynthesis.
• Oxygen is released during photosynthesis.

The process of photosynthesis can be represented as:

• The process of photosynthesis takes place in the green leaves of a plant.
• The food is prepared by the green leaves of a plant in the form of a simple sugar called glucose.
• The extra glucose is changed into another food called starch. This starch is stored in the leaves of the plant.
• The green plants convert sunlight energy into chemical energy by making carbohydrates.

The photosynthesis takes place in the following three steps:

1. Absorption of sunlight energy by chlorophyll.
2. Conversion of light energy into chemical energy, and splitting of water into hydrogen and oxygen by light energy.
3. Reduction of carbon dioxide by hydrogen to form carbohydrate like glucose by utilizing the chemical energy.

Conditions necessary for photosynthesis:
The conditions necessary for photosynthesis to take place are:

• Sunlight
• Chlorophyll
• Carbon dioxide
• Water
