Question

What is photosynthesis ???? ​

Answer 1

Answer:

The process by which green plants and some other organisms use sunlight to synthesize in plants generally involves the green pigment chlorophyll and generates oxygen as a by-product

Answer 2

Explanation:

The process in which green plant synthesis their food like glucose from CO2 (Carbon dioxide) and H2O (water) in the presence of sunlight with the help of chlorophyll.

6CO2 + 12H2O (in the presence of light and chlorophyll) → C6H12O5 (glucose) + 6H2O + 6O2

Necessary things for photosynthesis:

1. Carbon dioxide
2. Water
3. Chlorophyll
4. Sunlight

• Terrestrial plants take CO2 from atmosphere while aquatic plants use CO2 dissolved in water.
• Photosynthesis convert light energy into chemical energy.
• The stages of photosynthesis

1. Photochemical reaction or light reaction
2. Dark chemical reaction

• Chlorophyll absorb tr violet, blue and red colors of light.
• Most common type of chlorophyll that found in plants are chlorophyll 'a' and 'b'.
• Water is necessary for photosynthesis and is absorbed by the roots of the plants.
• Oxygen that is produced during photosynthesis is because of photolysis of warer.
