21. You see a moss plant near the base of a tree in your yard. The green "leafy" plant that you can see without magnification is the: A. Gamete B. Zygote C. Gametophyte D. Spore E. Sporophyte 22. What features do ferns and bryophytes share? A. the sporophyte and gametophyte are independent B. dispersal is accomplished with seeds C. well developed vascular tissues D. water is required for fertilization E. all of the above 23. Why was the evolution of pollen beneficial for plants? A. it freed plants from needing moisture for fertilization B. it helped enhance dispersal on land C. it provided extra nutritional resources for the embryonic plant D. it helped to separate the reproductive and growing phases of the plant's life cycle E. it helped attract pollinators to consume the nectar within the flowers

QUESTION 21 Each of the following is true about the life cycle of the mosses except external water is required for fertilization flagellated sperm are produced archegonia and antheridia are produced by gametophytes gametes are produced by meiosis QUESTION 22 A botanist discovers a new species of plant in a tropical rainforest. Its characteristics include flagellated sperm, presence of xylem for conducting water, independent gametophyte and sporophyte stages, no seeds. This plant is most likely a moss liverwort fern multicellular green alga QUESTION 23 What structures allow vascular plants to readily take up carbon dioxide from the atmosphere? stomata cuticles gametangia chloroplasts QUESTION 24 In plants, gametangia are structures that contain the gametophyte generation that produce and protect sperm and egg within a jacket of sterile cells that act as gametes that fuse with each other to form the zygote QUESTION 25 Sori, found clustered on the underside of fern leaves, are clusters of sporangia gametangia gametophytes archegonia

11. In angiosperms, pollination results in the delivery of sperm cells to the ovary. Afterward, what happens? a. Fertilization occurs, resulting in a triploid zygote. b. Meiosis occurs, resulting in 3 haploid zygotes. c. Mitosis occurs, resulting in a larger endosperm. d. Double fertilization occurs, resulting in a zygote and triploid endosperm. e. Double fertilization occurs, resulting in a diploid endosperm and haploid zygote. 12. Fruits are important innovations in the success of angiosperms because they promote cross-pollination and gamete exchange, they supply nutrients to the plant, and they promote seed dispersal. 13. 'Alternation of Generation' in plants can be accurately described as follows: - Some adult plants are sporophytes, and some are gametophytes. - Plants are haploid but alternate which chromosomes are in cells. - Haploid gametophytes and diploid sporophytes are both independent and macroscopic. - Haploid and diploid forms are in different parts of a plant. - Plants are always diploid, but some are small, and some are large.
