Question

I need a short answer for each question please.

Question 8: Water lilies, like the name implies, live in water, like ponds. They are flowering plants that make seeds, so are part of the land plant group. How can this be? Question 9: Consider the bryophyte life cycle. How is a sporophyte formed? Question 10: Some seeds can exist in a dry state for a very long time, seemingly not even alive, but then germinate when conditions are right. How might this be an adaptive advantage for species of plants that live in very harsh environments?

Answer 1

8. The water lily is an angiosperm (Land plant group)
a. It produces flowers
b. It produces fruits
c. It exhibits double fertilization

9. Bryophytes exhibit a haplodiplontic life cycle.
i.e. The gametophyte is dominant and the sporophyte is dependent on the gametophyte for attachment and nutrition.
The gametophyte produces gametes by mitotic division. The egg cell in the archegonia is fertilized by the male gamete to produce a diploid zygote.
The zygote produces the multicellular diploid sporophyte by mitotic divisions.

10. Seeds provide an adaptive advantage.
a. They help a plant to disperse into new habitats
b. They help to survive adverse conditions by exhibiting dormancy
