what is photosynthesis explain its mechanism? koi h online
Answers
Answer:
Photosynthesis is the process by which green plants prepare their food in the presence of sunlight. Green plants utilize carbon dioxide and water to make carbohydrate. The reaction of photosynthesis can be depicted in the following equation:
6CO2+12H2Ochlorophyll+sunlight
C6H12O6+6O2+6H2O
The process of Photosynthesis is composed of following step:
(a) Absorption of light energy by chlorophyll.
(b) Conversion of light energy into chemical energy
(c) splitting of water molecules into hydrogen and oxygen.
(d) Reduction of carbon dioxide to form carbohydrate
These steps need not take place one after another immediately. For example; desert plants take up carbon dioxide at night to make an intermediate. During daytime. they make carbohydrate. After photosynthesis, carbohydrate is converted into starch and starch is stored in different plant organs.
Answer:
Photosynthesis is a method of transforming light energy into chemical energy by phototrophs, which is later used to fuel cell functions. Chemical energy is stored in the form of sugars, which are generated from carbon dioxide and water. Algae also use photosynthesis to turn solar energy into chemical energy.
