Summary Introduction
Introduction:
Chlorophyll and carotenoid pigments of photosystem II absorb light that energies and ejects an electron from a reaction center “chlorophyll a molecule”. Carotenoids help plants in photosynthesis and protect them from photodamage. Some examples of carotenoids are beta-carotene and lycopene. They are present in the stem, leaves, fruits, and other parts of the plant.

Why do desert plants that live in very hot and dry conditions have stomata? a. To allow for transpiration b. To allow for gas exchange c. To allow for the release of excess heat d. Both a and b are correct.
You decide to plant a garden with a beautiful black walnut tree at one end and a majestic white oak at the other end. You are quite disappointed, however, when none of the seeds you plant around the walnut tree grow. What might explain this observation?
a. The walnut tree filters out too much light, so the seeds fail to germinate.
b. The roots of the walnut tree deplete all of the nutrients from the soil, so the new seedlings starve.
c. The walnut tree produces chemical toxins that prevent seed germination.
Which of the following statements is incorrect?a. Pigments absorb light of certain wavelengths only.b. Some accessory pigments are antioxidants.c. Chlorophyll is green because it absorbs green light.
