_____ 1. Based on data represented by the graph, which colors and wavelengths of light appear to be most valuable to the process of photosynthesis?
a. yellow (550-575 nm) and orange (600 – 625 nm)
b. green (500 – 550 nm) and yellow (550 – 575 nm)
c. blue (425 – 475 nm) and red (625 – 700 nm)
d. blue (425 – 475 nm) and violet (375 – 425 nm)
_____ 2. Certain types of primitive algae photosynthesize using light only in the yellow-orange range. What could one conclude from this information?
a. these algae must contain large concentrations of chlorophyll a
b. today’s land plants must have evolved from primitive algae
c. other pigments besides chlorophyll must take part in photosynthesis
d. these organisms require very bright light during photosynthesis
_____ 3. In what way is the process of photosynthesis similar to the process of cellular respiration? Both processes:
a. release carbon dioxide
b. involve mitochondria
c. utilize light energy
d. require enzymes
