Question

Some photosynthetic organisms contain chloroplasts that lack photosystem II, yet are able to survive. The best way to detect the lack of photosystem II in these organisms would be

• A. to determine if they have thylakoids in the chloroplasts.
• B. to test for liberation of O2 in the light.
• C. to test for CO2 fixation in the dark.
• D. to do experiments to generate an action spectrum

Answer 1

The correct option is B

to test for liberation of O2 in the light.

Oxygen is released during non-cyclic photophosphorylation in which both PS1 and PS 2 are involved.
