Question

What is Photosynthesis?​

Answer 1

Photosynthesis : The process by which autotrophs take in substances from the outside (in the form of CO2 and H20) and convert them into stored forms of energy (Carbohydrates) in the presence of sunlight and chlorophyll. Carbohydrates.

Explanation :

Note: Carbohydrates are utilised for providing energy to the plant. The carbohydrates which are not used immediately are stored in the form of starch, which serves as the internal energy reserve to be used as and when required by the plant.

• Remember: In animals and in our body, energy is stored in the form of glycogen.

The following events take place during photosynthesis :

1. Absorption of light energy ( by chlorophyll ).
2. splitting of water molecules into hydrogen and oxygen ( photolysis of water ).
3. Conversion of light energy to chemical energy ( in the from of ATP and NADPH ).
4. Reduction of CO2 to Carbohydrates ( assimilation of carbon ).

The following reaction take place :

6CO2+6H2O⸻➤C6H12O6+6O2

• In the pressence on chlorophyll and sunlight.

Answer 2

Answer:

To make oxygen and energy in the form of glucose plants use sunlight, carbon dioxide, and water, this process is called photosynthesis.

Explanation:

This process helps to maintain the oxygen and carbon dioxide level. Light intensity, the concentration of carbon dioxide, and temperature can affect the rate of photosynthesis. The equation for photosynthesis is:

$6CO_2+6H_2O$⇒$C_6H_1_2O_6+ 6O_2$

This equation implies that 6 molecules of carbon dioxide and 6 molecules of water react in presence of sunlight and convert into one glucose and 6 oxygen molecules.
