Dependence on water for sperm transport

Question 6

Which statement best describes the difference between a seed and a spore?

Question 10

Which of the following is an example of a multiple fruit, and how does it develop?

Accepted Answer

Pineapple; develops from the fusion of ovaries from multiple flowers

Question 11

Which of the following best illustrates the concept of 'alternation of generations' in plants?

Accepted Answer

A diploid sporophyte produces haploid spores, which grow into haploid gametophytes that produce gametes.

Question 12

Which of the following best explains how animals have influenced the evolution of terrestrial plants?

Accepted Answer

Animals have driven the evolution of flowers and fruits to enhance pollination and seed dispersal.

Question 13

Which of the following is true regarding monoecious and dioecious plants?

Accepted Answer

Monoecious plants have both male and female flowers on the same individual, while dioecious plants have male and female flowers on separate individuals.

Question 14

Which adaptation is most directly responsible for the success of seed plants in dry terrestrial environments?
