Seedless Plants Review Questions Draw an alternation of generations life cycle for plants that have only one kind of spore (both sexes in the same individual).  In the alternation of generations life cycle, what is the function of the gametophyte? Name the structure that produce reproductive cells (sperm, eggs, and spores) in moss and ferns.  Which of the major groups of plants have swimming sperm? Which do not? For each of the major groups of plants (nonvascular, vascular seedless, gymnosperms, angiosperms), tell what generation (sporophyte or gametophyte) is dominant. Give an example of a plant for each of the four major groups of plants listed above. Which group includes mosses? Which group includes ferns? Name the kinds of vascular tissue found in vascular plants. What kinds of plants do not have true roots, stems, or leaves? Describe the sporophyte and gametophyte of a moss and of a fern.   Seed Plants Review Questions Draw an alternation of generations life cycle for seed plants (they have megaspores and microspores). Describe pollination. Where (what structure) are each of the following found in flowering plants and in gymnosperms: pollen grains, microspore, seed, microsporangium. List characteristics of seed plants. How do they compare with seedless plants? Name the major groups of gymnosperms. Name the generation that is contained within a pollen grain. Identify the structures on the diagram below. What major group of plants is it from. How do monocots differ from dicots?  Be able to draw a flower and name the parts. Name the differences between angiosperms and gymnosperms. State the function of endosperm. Describe the process of double-fertilization in angiosperms. Name the structures in a flower that eventually become a part of the seed. Describe the structure and function of a seed coat. Describe a simple fruit, an aggregate fruit, and a multiple fruit.  What major group of plants is the structure shown below from. Identify A and B 10.  What major group of plants is this structure found in. Identify A through F.   Review Questions- Introduction to Animals, Sponges, Cnidarians What phyla of animals have a segmented body plan? How does a complete digestive tract differ from a sac-like digestive tract. What phyla of animals have no tissue layers? 2 embryonic tissue layers? 3 embryonic tissue layers? List characteristics of sponges. Distinguish between (or describe) a polyp and a medusa in Cnidarians. Describe the life cycle of an animal. Describe the mode of nutrition of animals (are they heterotrophs or autotrophs?) Describe how a Cnidarian feeds. What phyla of animals are bilaterally symmetrical in either the adult or the larval stage? What phyla (or phylum) of animals are radially symmetrical?   Procaryotes Review Questions Name the organelles found in a prokaryotic cell. Name the genetic material of prokaryotes (DNA, RNA, or some other molecule). Describe three kinds of genetic recombination in bacteria. State the function of an endospore. What is a nucleoid? Describe how chemosynthetic bacteria obtain their energy and how they obtain their organic nutrients (food). Describe how heterotrophs obtain their energy and how they obtain their organic nutrients (food). Describe cell division in prokaryotes.
