Question

what is photosynthis​

Answer 1

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.

Equation:

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

Necessary things for photosynthesis:

• Carbon dioxide
• Water
• Chlorophyll
• 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

Photochemical reaction or light reaction

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.

Answer 2

Explanation:

The chemical process through which green plants ( containing chlorophyll) combine carbon dioxide and water in the presence of sunlight to prepare food in the form of glucose is called Photosynthesis.
