Question

define photosynthesis ...​

Answer 1

Answer:

Photosynthesis, the process by which green plants and certain other organisms transform light energy into chemical energy. During photosynthesis in green plants, light energy is captured and used to convert water, carbon dioxide, and minerals into oxygen and energy-rich organic compounds.

Answer 2

Answer: The process during which simple inorganic compounds like carbon dioxide (CO₂) and water combine in presence of sunlight and chlorophyll to produce complex organic molecule called glucose ( C₆H₁₂O₆ ) with the liberation of oxygen (O₂) is called photosynthesis.

Explanation:

• The process of preparation of food materials by the plants in presence of sunlight, carbon dioxide, water, chlorophyll is simply called photosynthesis.
• It is a photo chemical reaction during which solar energy is converted into chemical energy.
• The process formula is given as:

        6CO₂ + 6H₂O  → C₆H₁₂O₆ + 6O₂ + 6H₂O

• (Carbon dioxide)  +  (Water)  →  (Glucose)    +   (Oxygen)   +   (Water)
• Thus the definition becomes, the process during which simple inorganic compounds like carbon dioxide (CO₂) and water combine in presence of sunlight and chlorophyll to produce complex organic molecule called glucose ( C₆H₁₂O₆ ) with the liberation of oxygen (O₂) is called photosynthesis.
