Suppose an efficient conducting system evolved in a moss thatcould transport water and other materials as high as a tall tree.Which of the following statements about “trees” of such aspecies 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 foraccess to light.
In a young anther, a group of compactly arranged homogenous cells were observed in the centre of each microsporangium. What is the name given to these cells?
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 elsewherearrow_forwardWhich of the following lettered structures would contain microsporangia?arrow_forwardsporangiophores 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. (See text Figure 17-40 and 17-41, page 425-427.) Photo by Carolyn Alling Fill in Table 1 from the Bryophyte lab with information about Lycophytes, Ferns, and Horsetails. 97arrow_forward
- Under the topic colonization of land plants, land plants are said to have derived traits which include walled spores produced in sporangia. How does this differentiate from similar traits in charophytes?arrow_forwardRead these two statements about plant-fungal interactions, then pick the statement below that is TRUE. (A) Root fungi in phylum Ascomycota can cause plants to produce antioxidants that provide protection against the stress of drought, and plants feed carbon to the fungi in their roots. (B) Root fungi and plants have evolved mutual benefits through a long history of interaction, in which fungi that provided the greatest benefits to plants had the highest fitness because of the carbon the plants fed them, and plants that supported fungi had the highest fitness because of the protection provided by the fungi. (A) is a proximate cause for plant-fungal symbiosis, whereas (B) is an ultimate cause. O (A) is an ultimate cause for plant-fungal symbiosis, whereas (B) is a proximate cause. Understanding plant-fungal interactions would NOT require cost-benefit analysis because there are no fitness trade-offs. (A) is an innate behavior and (B) is a learned behavior. O O O Oarrow_forwardSeeds and pollen grains are key adaptations for life on land. 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.

- Which of the following statements is accurate? a) All plants have identical sporangia, all producing the same type of spores b) Plants have an embryo that is protected inside (and nourished by) the gametophyte c) Gametangia produce gametes by meiosis whereas sporangia produce spores by mitosis d) Gametangia always produce haploid gametes whereas sporangia produce diploid spores e) Gametangia are multicellular structures whereas sporangia are unicellular structuresarrow_forwardWhich of the following characteristics of plants is absent intheir closest relatives, the charophyte algae?(A) chlorophyll b(B) cellulose in cell walls(C) sexual reproduction(D) alternation of multicellular generationsarrow_forwardThe waxy layer that covers aerial parts of plants is the (a) cuticle (b) archegonium (c) protonema (d) stoma (e) thallusarrow_forward
- Lichens are able to reproduce both sexually and asexually, with nearly 1/3 of all species reproducing solely by asexual means. Given that lichens are an association between multiple species from different kingdoms, how do you think this might work? What components would have to be present in the reproductive structure for reproduction to be successful?arrow_forwardWhat traits do bryophytes and tracheophytes have in common? Check all that you think apply.A) they both undergo alternation of generationsB) they both have chlorophylls a and b.C) they both have an asexual life cycle stage.D) they both have multicellular gametangiaE) they both have apical meristemsarrow_forwardWhen a fungus infects a plant, it (a) infiltrates leaves with lichens (b) forms relationships by attaching mycorrhizae to stems (c) secretes powerful digestive juices onto the leaves (d) uses haustoria to dissolve roots (e) enters leaves or stems through stomataarrow_forward
