2. All cells of the gametophyte are haploid. back to questions
3. Into what generation does the zygote develop? sporophyte back to questions
4. Which plant form is diploid? sporophyte back to questions
5. A saclike structure where pollen grains are produced is ... an anther back to questions
6. What is the difference between pollination and fertilization? Fertilization occurs after the pollen grain germinates and the pollen tube grows down to the ovary. The sperm nucleus then fertilizes the egg nucleus, and the embryo forms. Pollination occurs when pollen from the anther contracts the stigma of the female part of the plant. This can be accomplished by wind, insects, birds, or humans. back to questions
7. How do fruits aid in the dispersal of the seeds that they contain? Fruits aid in the dispersal of their seeds because they are attractive to animals that eat them but cannot digest the seeds. By the time the seeds have passed through the digestive system, they have been carried away from the parent plant. back to questions
