QUESTION 10

In CAM plants, there is a ______ separation between the light reactions and the Calvin Cycle.

spatial

temporal

light dependent reactions

Calvin cycle

Explanation / Answer

3. The correct option is Calvin cycle.

Water is used in the Calvin cycle of photosynthesis.

4. The correct option is The chlorophyll pigments absorb all wavelengths of light except in the green spectrum, which it reflects.

Chlorophyl absorbs violet and red, and reflects green. That's why, leaf appears green.

5. The correct option is C4 plants transfer fixed carbon dioxide from light reactions to different cells in which the Calvin cycle occurs.

First, atmospheric CO2 is fixed in the mesophyll cells. The CO2 is then fixed by rubisco and made into sugars via the Calvin cycle.

7. The correct option is Red ... green.

Red has longer wavelength than gree.
