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

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

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)
