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

- sporangiophores are interpreted as modified branches and consist of a stalk and a shield- like portion. Inside of the sporangium, look for the spores each with a pair of elongated appendages called elaters. These elaters respond to changes in the humidity to aid in spore dispersal. 18. Label the spores on Figure 6 below. Figure 6. Equisetum strobilius l.s. Equisetum is homosporous and produces green, free-living, bisexual gametophytes.

These adaptations relate to reproductive success and survival advantages. The following questions require you to explain some of these adaptations. A. Contrast sperm delivery in seedless plants with sperm delivery in seed plants. (5-6 sentence) B. Discuss at least one feature of seed plants that contributed to their success on land in contrast with seedless plants. (2-3 sentences) C. Flowering plants (Magnoliophyta) are the most successful of all plant groups in terms of their species diversity and ubiquity across habitat types. Climate warming is causing shifts in the timing of life history events for many species. Discuss how climate warming may influence reproductive strategies employed by flowering plants.

It is fall, and temperatures are dropping below freezing. The biologist cannot stay in the field to observe the plant. What can he infer about the plants reproductive strategy based on his recent observations? A) the plant will produce flowers because at this altitude there is sufficient sunlight B) the plant will produce comes because cones will mature into adult plants more rapidly C) the plant will produce cones because cones allow for seed dispersal through all seasons D) the plant will produce flowers because flowers can protect the seed from extreme conditionsarrow_forward
