BIO 152 Dr. Anastasia REVIEW SHEET – PRACTICAL EXAM I- Fall 2010 Lab 1- Data Analysis *know what independent and dependent variables are and be able to identify them if given an experimental design or a graph *know how to graph data and how to interpret graphs Lab 2- Ecology *know how to estimate population size using the mark-recapture technique and quadrat sampling *know how sample size affects percent error when estimating population size *know what allelopathy is and what species we found evidence of allelopathy in our experiment *know what competition is and under what conditions it will occur *be able to describe the possible effects of intraspecific competition in sunflower seedlings *know how structure in a habitat and prey behavior can influence predation rates- be able to cite the example from the experiment that we did Lab 3- Systematics *know the names of the taxonomic levels *be able to make a taxonomic key and to use one to identify organisms *know how to map character evolution on a phylogeny using the rules of parsimony *know how to read phylogenies- how to interpret evolutionary relationships from a tree Lab 4- Signaling Systems *For each of the following dissections, slides or models, know how to identify the structures listed and what their general functions are… Shark Brain dissection: Cerebrum, cerebellum, optic lobes, medulla oblongata Frog Brain dissection Cerebrum, cerebellum, optic lobes, olfactory lobes, medulla oblongata Sheep Brain dissection: Cerebrum, cerebellum, optic chiasma, pons, medulla oblongata, corpus callosum Human Brain Model: Cerebrum, cerebellum, pons, medulla oblongata, spinal cord, corpus callosum *know how the various sections of the vertebrate brain changed through evolution- be able to describe the trend *Know the effects of gibberellic acid on stem growth and seed germination BIO 152 Dr. Anastasia Lab 5- Reproduction *On the dissections and models, be able to identify the structures listed and know their main functions: Shark dissection; Claspers, testes, vas deferens (mesonephric duct), ovaries, oviduct, uterus Frog dissection: Ovaries, oviduct, testes, vas efferentia, fat bodies Rat dissection: Ovaries, oviduct (fallopian tubes), uterine horns, scrotal sacs, testes, epididymis, seminal vesicle, prostate gland, penis Human Torso model: Ovaries, oviduct (fallopian tubes), uterus, scrotal sacs, testes, epididymis, seminal vesicle, prostate gland, penis Lily model & live flowers: Anther, filament, stamen, style, stigma, ovary, ovules, pistil, petals *understand alternation of generations in plants and be able to identify the gametophyte and sporophyte stages in an angiosperm, a gymnosperm (pine tree) or in a pteridophyte (fern) *know what fragmentation and regeneration is and be able to describe the process in Planaria (including blastema formation) Lab 6- Development *be able to describe fertilization in sea urchins and how you can tell if the egg is fertilized (fertilization membrane) *know the basic stages of early animal development (cleavage, morula, blastula, gastrula) *know what cleavage is and how it both increases the number of cells and decreases the size of each cell *be able to identify the following stages on the prepared slide of starfish development: (egg, early cleavage stages (2-cell, 4-cell, etc), morula, blastula and gastrula) and know the process that leads from one stage to the next *be able to identify the following stages in the models of frog development: (morula, blastula, gastrula (ectoderm, mesoderm, endoderm, blastopore), neurula, tadpole) and know the process that leads form one stage to the next * model of the human placenta and developing embryo: extraembryonic membranes (the chorion, the amnion and the yolk sac), the placenta and the tissue layers of the embryo (endoderm, mesoderm and ectoderm) *know how the amount of yolk affects cleavage and gastrulation patterns *know the parts of a developing angiosperm, like your sunflowers (cotyledons, apical meristem, epicotyl, hypocotyl) *be able to identify the cotyledons, endosperm, radicle, shoot apex in corn and lima beans and know which seed is a dicot (bean) and which is a monocot (corn)
