Chapter 19, Problem 6WIO
A fern plant can produce as many as 50 million spores a year. (a) How are these spores similar to and different from seeds? (b) In a fern population that is neither shrinking nor growing, approximately what proportion of these spores is likely to survive long enough to reproduce? (c) What factors might determine whether an individual spore success fully produces a new fern plant?

- Which of the following comparisons between the moss life cycle and fern life cycle are correct? A) Mosses have flagellated sperm that need water to reach the female gamete, while the sperm of ferns are unflagellated and are not dependent on water.B) The sporophyte generation is smaller than the gametophyte generation in mosses, but the sporophyte generation is much larger than the gametophyte generation in ferns.C) The spores are produced in capsules on stalks in mosses but in small structures called sori on the underside of leaves in ferns.D) The gametes are produced in gametangia in mosses but in specialized structures on the underside of leaves in ferns.E) Both kinds of plants depend on wind for dispersal of spores.arrow_forwardWhat are 2 things that are true in both the plant life cycle and the human life cycle?
