Dr. A’s Lousy Review Sheet for Test 3 Please not that this just a GUIDE. Anything covered in class can appear on the test. PLANTS: Eukaryotic Photoautotrophic Multicellular Contain chloroplasts Chloroplasts contain chlorophylls a and b Cell wall made of cellulose Use starch to store energy Non-vascular : Gametophyte is dominant. Small, usually prefer shade. Have no protection against dessication. Require water for fertilization. 1. Hepaticophyta Liverworts. Sporophyte is microscopic, is formed under the umbrella-shaped things. 2. Bryophyta Mosses. Sporophyte consists of stalk and capsule, grows on top of gametophyte. Gametophyte has “stem” and “leaves”. Vascular : Invented LIGNIN, permitting hard stems and vessels. They have true tissues. These features in turn allow growth to very large sizes. SPOROPHYTE is dominant. 1. Seedless. FERNS were the only example studied. Sori, spores. The gametophyte is small, independent, and dies soon after the sporophyte starts growing. 2. Seed plants. FINALLY don’t depend on water for fertilization! Use wind or insects. GYMNOSPERMS have seeds but no fruit. We used Pine as the example. Male cone, female cone. The male gametophyte is a four-celled pollen grain. That kind of stuff. ANGIOSPERMS will not be on the test.
