Which of the following raw materials is available in the air for photosynthesis?
(a) Oxygen
(b) Carbon dioxide
(c) Nitrogen
(d) Hydrogen
Correct Answers: (b) Carbon dioxide
Explanation:
The word equation for the process of photosynthesis is:
Carbon dioxide + Water ----(Chlorophyll + Sunlight) ---> Glucose + Oxygen
The conditions necessary for photosynthesis are:
- Sunlight
- Chlorophyll
- Carbon dioxide
- Water
The factors that affect the rate of photosynthesis are:
- An appropriate amount of sunlight
- Availability of water
- Availability of carbon dioxide
