Q30. When a culture of Chlamydomonas cells is placed in a Petri dish and exposed to HIGH intensity light, the cells will migrate away from the light. They move away from the light because the light is potentially harmful. How could high intensity visible light be harmful? A. High light can randomly ionize membrane lipids causing their breakdown. B. High light can heat up the cells causing protein denaturation. C. High light can donate electrons from photons to O2 producing reactive oxygen molecules. D. High light can increase the amounts of P680+, which is potentially harmful.

Discuss Concepts Like other accessory pigments, the carotenoids extend the range of wavelengths absorbed in photosynthesis. They also protect plants from a potentially lethal process known as photooxidation. This process begins when excitation energy in chlorophylls drives the conversion of oxygen into free radicals, substances that can damage organic compounds and kill cells. When plants that cannot produce carotenoids are grown in light, they bleach white and die. Given this observation, what molecules in the plants are likely to be destroyed by photooxidation?
