Life Processes (C10)

(a) Name the process and explain the type of nutrition found in green plants. List the raw materials required for this process. Give chemical equation for the mentioned process.

(b) Write three events that occur during this process.


a) Process: Photosynthesis

Type of Nutrition: Autotrophic Nutrition

Explanation: Autotrophic nutrition is the process where plants prepare their own food, using inorganic material such as CO2 and H2O in presence of Sunlight and Chlorophyll.


Raw material: CO2, H2O

b) Three events:

  1. Absorption of light energy by chlorophyll
  2. Conversion of light energy to chemical energy and splitting of water molecules into hydrogen and oxygen
  3. Reduction of Carbon dioxide to Carbohydrates
