What patterns of reproduction and development are found in plants and animals and how are they regulated?
A. All plants (and some protists, i.e.Chlorophyta) show a reproductive pattern known as alternation of generations. However, plants have modified this pattern through evolution and you should be able to explain how alteration of generations differs in: mosses, ferns, gymnosperms, and angiosperms. B. Some flowering plants use the photoperiod (the amount of light and dark received during a 24 hour period). See pages 821-823. PLEASE READ THIS CAREFULLY! C. Animals also show diverse patterns of reproduction. Three major patterns follow. Be able to give examples of organisms that use each of these and describe the advantages and disadvantages of each. external fertilization and external development internal fertilization and external development internal fertilization and internal development D. Human females have a reproductive cycle that is slightly different than that of most other mammals. See figure 46-15 on page 988 and be prepared to answer questions about regulation of the cycle. E.
