Consider a puddle of water in which mosses, ferns and an angiosperm are growing. In a drop of water taken from the puddle, you observe flagellated sperm.
Which of the following statements concerning the sperm could be true and which are definitely false?
a.The sperm could have been produced by an antheridium on the moss sporophyte. True/False? Explain.
b.The sperm could later stop swimming and develop into the male gametophyte of the fern. True/False? Explain.
c.The sperm may be swimming to the archegonium of the fern. True/False? Explain.
d.The sperm could have been released from a pollen tube of an angiosperm. True/False? Explain.
Homework Answers
1) False [ The sperm produced by an antheridium on the moss Gametophyte not sporophyte]
2) False [. The sperm later reach to the archegonium and develop into the sporophyte of the fern ]
3) True [The sperm may be swimming to the archegonium of the fern]
4) .False [ Angiosperm doesn't have motile flagellated sperms

Which of the following sets of statements is true? In mosses, the gametophyte is the dominant stage of the life cycle; in ferns, the sporophyte is the dominant stage of the life cycle. Ferns require moisture for sperm to reach the egg, but mosses do not. The gametophyte is the dominant stage of the life cycle in both mosses and ferns. Mosses require moisture for sperm to reach the egg, but ferns do not. In mosses, the sporophyte is the...

Name the gametophyte structure and the sporophyte structure of both bryophytes and ferns. Also know whether they are haploid or diploid, and which is the more easily recognized (dominant). Be able to tell which gametangia the reproductive structures of moss and ferns are (archegonium or antheridium). Know the terms: rhizoid, rhizome, gemmae cups, prothallus, sorus, sporangia, alternation of generations (explain what it is)

In ferns, both the gametophyte and sporophyte are physiologically capable of surviving on their own. Which of the following are reasonable hypotheses for why vascular tissues are present only in the sporophyte generation? Select all that apply. There is no advantage for the gametophyte to grow tall, because fern gametophytes typically produce only male or female gametes at any one time There is no advantage for the gametophyte to grow tall, because gametes must be produced near the ground where...
