Question

what is photosynthesis?​

Answer 1

Explanation:

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

Answer 2

Answer:

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 is known as photosynthesis.

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 the 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.
