Question

what is photosynthesis​

Answer 1

Answer:

the process by which green plants turn carbon dioxide and water into food using energy from sunlight

Answer 2

Photosynthesis

• The process by which green plants prepare their own food by using carbon dioxide and water in the presence of sunlight.
• Oxygen and vapours are released as by-products.

Raw materials for Photosynthesis

• Carbondioxide from air
• Water from soil

Products of Photosynthesis

• Carbohydrate (main product)
• Oxygen (by-product)
• Water vapours

Additional Points

• The initial product of photosynthesis is a carbohydrate-glucose which gets converted into starch.
• Carbohydrates contain carbon,hydrogen and oxygen.
• Some carbohydrates are also converted yo proteins and fats.
• Besides carbon, hydrogen and oxygen, proteins and contains nitrogen.

Photosynthesis is a unique process because its supplies food, directly or indirectly, for all living organisms. The energy of the sun, thus, get passed on to all organisms through plants. Plants also provide oxygen, needed by all living oraganism for respiration.
