FAQs on Photosynthesis in Higher Plants Class 11 Notes

1. What is the significance of photosynthesis?

Photosynthesis is essential for producing oxygen and glucose, which are necessary for the survival of all aerobic organisms.

2. Why do plants have different pathways like C3, C4, and CAM?

These pathways help plants adapt to different environmental conditions such as temperature, water availability, and light intensity.

3. How do external factors affect photosynthesis?

Light intensity, CO2 concentration, temperature, and water availability play crucial roles in the rate of photosynthesis.

4. What is the difference between cyclic and non-cyclic photophosphorylation?

Cyclic photophosphorylation produces only ATP, while non-cyclic photophosphorylation produces both ATP and NADPH.

5. Can photosynthesis occur without sunlight?

No, sunlight is essential for initiating the light reaction of photosynthesis.
