Explanation / Answer

11. What role do diatoms play in the global carbon balance affecting global warming?

D) During a bloom, diatom populations may increase rapidly. If many diatoms die and sink to the bottom without being eaten, they effectively pump carbon dioxide out of the atmosphere.

12. Which of the following groups of algae is/are most closely related to higher plants?

B) Green algae

13. In life cycles with alternation of generations, multicellular haploid form alternate with
