- If ferns produce spores, are they a sporophyte or agametophyte? Are they haploid or diploi Describe two differences between a fern sporophyte and a moss sporophyte. Are fern spores haploid or diploid? Are the spores produced by meiosis or mitosis? Where are the spores produced?arrow_forwardIn animals, meiosis produces gametes (sperm cells and egg cells), but that does not happen in plants. When some of the cells of a sporophyte undergo meiosis, what types of cells are produced? What do they grow into?arrow_forwardIs the possession of flagellated sperm a primitive or advanced characteristic in the plant kingdom? Why?arrow_forward
- In the vascular bundles of flowering plants, protoxylem is closest to the center of the stem, and metaxylem is farther out. Is this an endarch or an exarch arrangement? Seed plants always have just this one arrangement, but what about the early vascular plants? Were they endarch or exarch, or did both types occur originally?arrow_forwardWhere are bulliform cells found in leaves?arrow_forwardIn the vascular bundles of flowering plants, protoxylem is closest to the center of the stem, and metaxylem is father out. Is this an endarch or an exarch arrangement, but what about the early vascular plants. Were they endarch or exarch, or did both types occur originally?arrow_forward
- There are two alternative hypotheses about the life cycle of the early vascular plants, the transformation hypothesis and the interpolation hypothesis. If Rhynia and Sciadophyton are the two generations of one species, which hypothesis would be favored? Briefly describe the other hypothesis.arrow_forwardDo mosses have an alternation of isomorphic or heteromorphic generations? That is, can you easily tell a moss gametophyte from a moss sporophyte? When we look at leafy green moss plants, what are we seeing—the gametophyte or the sporophyte? In a flowering plant species, would the equivalent stage be the plant or the pollen grains and megagametophytes?arrow_forwardAre fern spores haploid or diploid? Are the spores proudced by meiosis or mitosis? Where are the spores produced?arrow_forward
- 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.arrow_forwardWhich are the beings that form the kingdom Plantae? Are algae part of this kingdom?arrow_forwardUnder 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_forward
