13. “Most plants exhibit indeterminate growth.” What does this
statement mean? Do animals generally
exhibit indeterminate growth? If so, provide an example of indeterminate growth
in an animal species? Why is it important for plants to have indeterminate

14. What is meant by the terms “phenotypic plasticity” and “morphological
diversity”? Give examples of phenotypic plasticity in shoots and in roots. Do
animals exhibit phenotypic plasticity? Explain your answer. Give examples of
morphological diversity in roots and in shoots.

15. What are apical meristems, where are they located, and what is
their role in primary growth? What is cellular differentiation? How do primary
meristem cells and apical meristem cells differ?


16. What is the difference between sexual reproduction and asexual
reproduction? For plants, what is the main advantage of sexual reproduction,
and what is the main advantage of asexual reproduction? Can any animals
reproduce asexually? [Hint: look up “parthenogenesis” and “budding” in your
textbook and/or on line.]

17. What are the four primary organs that make up a flower? What is
the function of each? Does every flower have all four organs?

18. What is the “alternation of generations” in plants? How does
alternation of generations in plants differ from gamete production in humans? What
is a sporophyte? Are sporophyte cells diploid or haploid? What is a
gametophyte? What is its ploidy? Are sporophytes and/or gametophytes
unicellular or multicellular? How are male and female gametophytes formed in
angiosperms? When during development is each formed?

19. What is the primary advantage of cross pollination over self
pollination? Of self pollination over cross pollination? How is self
pollination avoided in some plants that have “perfect” flowers?
