Chapter 29, Problem 5TYU
Suppose an efficient conducting system evolved in a moss that could transport water and other materials as high as a tall tree. Which of the following statements about “trees” of such a species would not be true?
(A) Spore dispersal distances would probably increase.
(B) Females could produce only one archegonium.
(C) Unless its body parts were strengthened, such a“tree” would probably flop over.
(D) Individuals would probably compete more effectively for access to light.

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.
Your class is studying the burrs – the seed pods – of the common burdock plant. Your lab partner notices that the burrs easily cling to clothing, as well as to each other, and that some of the spines have come loose and gotten stuck in her skin, which is somewhat painful. Based on these observations, is there a logical explanation, other than reproductive success, for why the seed might have this special structure?
(a) Yes, the structure may help the seed cling to the soil so that it can take root more easily
(b) yes, these structures may prevent the seeds from getting damaged or eaten by other animals
(c) yes, the structures may help prevent the seeds from getting pulled from the plant by sticking to each other
(d) No, they are obviously intended to attach to animals so that they can be carried and dropped elsewhere
