- Figure 23.28 Which of the following statements about the Laminaria life cycle is false? In zoospores form in the sporangia. The sporophyte is the 2n plant. The gametophyte is diploid. Both the gametophyte and sporophyte stages are multicellular.Which of the following is NOT a gymnosperm? O lily gingko U cycad gnetophyteYou have discovered a new plant species that you think may be a gymnosperm. Which of the following features would you NOT expect it to have? Cones Fruits Vascular tissue like xylem and phloem Seeds
- Flowering plants are greatly different from conifers and other gymnosperms in their: O Parenchyma, especially sclerids with druses O Seed coat, but only the part derived from the integument O Collenchyma, especially suspensors with triploid endosperm O Vasculature, especially vessels with perforation platesWhen two gametes come together from different plants, the zygote matures into a: Sporophyte O Gymnosperm O Bryophyte O AntheridiumHow different are theendosperm of gymnospermsand the endosperm ofangiosperms?
- When looking at any gymnosperm, you would be observing the generation. O Sporophyte O Gymnosperms do not have gametophytes or sporophytes O GametophyteWhich allows gymnosperms to get their sperm to their eggs without environmental water? O pollen O flowers O all of these answers are correct vascular tissue O fruits 99+The classification of the seed plants has varied. If a person groups all seed plants together in one large Division Spermatophyta, then they have two classes—the class with naked seeds and the class , plants with carpels. On the other hand, many people (and this book) use four divisions, not one. List the three divisions of “gymnosperms” and the one division of flowering plants.
- Which of the following is found in angiosperms, but not gymnosperms? sexual reproduction using flowers a vascular system a root system to transport water and nutrients O seeds that disperse the parent plant(rather than herbaceous) in that the xylem often displays secondary growth (widening of the trunk). They generally have only tracheids for water conduction and lack vessel elements, which are characteristic of angiosperms. Tyino I. Division: Cycadophyta Although there is only about 100 extant species of cycads, this phylum was significant during the Triassic period (248 million years ago). They are tropical and subtropical plants with trunk-like stems and compound leaves and are popular as ornamentals. These plants are dioecious in that seed cones and pollen cones are on two separate plants. Because of their palm-like structure, they are sometimes incorrectly described as palm trees. However, like other gymnosperms they produce cones and lack flowers. Examples of cycads include False king sago and Florida coontie (Zamia pumila). Zamia pumila is the only cycad native to the United States. ACTIVITY 1: Examine the live plant and/or cones if available.
