1. What is Photosynthesis? Explain the process of photosynthesis.
Photosynthesis is a biological process utilized by all green plants to synthesize their own nutrients. The process of photosynthesis requires solar energy, water and carbon dioxide. The by-product of this process is oxygen.
Q2
2. What is the significance of Photosynthesis?
During photosynthesis, oxygen gas is liberated out into the environment and is utilized by humans, animals and other living species during the process of respiration.
Q3
3. List out the factors influencing Photosynthesis.
There are several factors that affect the rate of photosynthesis. Light intensity, water, soil pH, carbon dioxide concentration, temperature and other climatic conditions are the main factors affecting the rate of photosynthesis.
Q4
4. What are the different stages of Photosynthesis?
Photosynthesis takes place in two stages, namely light-dependent reactions and light-independent reactions. Light-dependent reactions are also called light reactions and occur during the day time. Light-independent reaction is also called the dark reaction or the Calvin cycle.
Q5
5. What is the Calvin Cycle?
The Calvin cycle is also called the light-independent reaction. The complete process of the Calvin cycle takes place in the stroma of the chloroplasts.
Q6
6. Write down the Photosynthesis Equation.
6CO2 + 6H2O —> C6H12O6 + 6O2
