D. All of these E. Both A and B.
8. The term monoecious refers to
A. plants that produce a single terminal flower at the end of each stem.
B. only one type of flower per plant – either male flowers or female flowers, but not both.
C. plants that flower only once in a lifetime.
D. plants that self-pollinate.
E. plants possesing separate male and female flowers (on the same plant).
9. Suppose that a plant incurs a mutation which prevents it from producing synergids. What would be
the most likely consequence?
A. The plant would not produce flowers
B. The plant would produce flowers, but they would be self-incompatible.
C. The plant would not be able to engage in cation exchange.
D. The frequency of fertilization would be reduced.
