describe the process of photosynthesis in 3 steps
Answers
Answer:
Photosynthesis is a complex process that can be divided into two or more stages, such light-dependent and light-independent reactions. The three-stage model of photosynthesis starts with absorption of sunlight and ends in the production of glucose.
Explanation:
Stage 1: Harvesting Radiant Energy
When a beam of sunlight hits a green, leafy plant, the process of photosynthesis is set in motion.
Stage 2: Converting Radiant Energy
After radiant energy from sunlight is absorbed, the plant converts light energy into a usable form of chemical energy to fuel the plant’s cells.
Stage 3: Storing Radiant Energy
The last stage of the photosynthesis process is known as the Calvin-Benson cycle, in which the plant uses atmospheric carbon dioxide and water from soil to convert ATP and NADPH. The chemical reactions that make up the Calvin-Benson cycle occur in the stroma of the chloroplast.
Explanation:
The three events that occur during the process of photosynthesis are:
i) Absorption of light energy by chlorophyll.
ii) Conversion of light energy to chemical energy and splitting of water molecules into oxygen and hydrogen.
iii) Reduction of carbon dioxide to carbohydrates.
