Mid Term Exam Review Sheet
You should be familiar with material from the following units, especially the terms
and ideas listed below. The test will consist of multiple choice, free response and
essay questions. There will also be a reading comprehension section on the test.
Living things, scientific method: Be able to use and define the following terms:
Spontaneous generation, homeostasis, problem question, hypothesis, experiment, data,
conclusion, independent variable, dependent variable, control, cell, reproduction,
response, ATP
Be able to explain Francesco Redi’s experiment that disproved spontaneous generation
Be able to explain Louis Pasteur’s experiment that also disproved spontaneous generation
Know that the independent variable should be graphed on the X-axis of a graph and the
dependent variable should be graphed on the Y-axis of a graph.
Know the differences between plant and animal cells.
Know cell theory:
1. Cells are the basic unit of structure and function of every living thing
2. All living things are made of at least one cell
3. All cells come from pre-existing cells
Know the difference between prokaryotic and eukaryotic cells
Know the hierarchy of living things celltissueorganorgan systemorganism. Not
all living things have all of these levels of organization, but all organisms have cells.
Know about cellular processes such as diffusion, osmosis, respiration, photosynthesis.
Cells: Be able to use and define the following terms:
Cell membrane, cell wall, nucleus, cytoplasm, chromosome, DNA, ribosome,
mitochondria, chloroplast, vacuole, golgi bodies, endoplasmic reticulum, osmosis,
diffusion, active transport, ATP, meiosis, mitosis, asexual reproduction, autotroph,
heterotroph, respiration, fermentation, endocytosis, exocytosis, gamete, haploid, diploid,
enzyme, metabolism, prophase, metaphase, anaphase, telophase, interphase, mutation
Know the difference between mitosis, meiosis and asexual reproduction
Know the steps of mitosis
Know the difference between haploid and diploid cells. Know that there are 46
chromosomes in a diploid human cell
Know why it is necessary to reduce the chromosomal number in gametes by meiotic
division
Genetics/ heredity: Be able to use and define the following terms.
Genetics, gene, chromosome, DNA, RNA, allele, trait, dominance, recessive, genotype,
dominance, multiple alleles, pedigree, sex-linked trait, transcription, translation,
replication, semi-conservative, replication, nucleotide, ribose sugar, deoxyribose sugar,
adenine, guanine, cytosine, thymine,
Know how to do a Punnett square and use it to predict outcomes of genetic crosses
Know how incomplete dominance or multiple alleles can affect the outcome of a genetic
cross
Know how the steps of protein synthesis are related to each other.
Be able to describe the structure of DNA
Be able to correctly pair the nitrogenous bases: adenine with thymine, guanine with
cytosine.
Be able to describe replication, transcription and translation.
Taxonomy: Be able to list and sequence the various levels of taxonomic hierarchy. Be
able to write a scientific name in correct binomial nomenclature. Be able to read a simple
dichotomous key.
Know the 6 Kingdoms of living things and how they are different from each other. Be
able to compare and contrast the similarities and differences between all 6 Kingdoms.
Be able to correctly write a name in binomial nomenclature. Be able to assess the
relatedness between organisms based on their genus and species
The Bacterial Kingdoms: Be able to define prokaryotic and associate the term with the
bacterial Kingdoms. Understand the difference between the archeobacteria and the
eubacteria. Be able to compare and contrast prokaryotic and eukaryotic cells
Be able to create a Venn diagram comparing and contrasting prokaryotic and eukaryotic
cells.
The Protist Kingdom: Know that the protists are single celled and eukaryotic. They
may be either heterotrophic or autotrophic. They are the forerunners of the three
multicellular Kingdoms.
The Fungus Kingdom: Know that most fungus are multicellular (yeasts are the
exception) and that they are heterotrophic and eukaryotic. Their cell walls are made of
chitin.
The Plant Kingdom: Know that plants are multicellular autotrophs with cell walls made
of cellulose. They are eukaryotic. They have large vacuoles and chloroplasts.
Be able to distinguish between angiosperms and gymnosperms. Be able to identify the
different tissues in a vascular plant (Plant structure lab and Flower lab) Be able to discuss
adaptations that enabled plants to move on to dry land.
The Animal Kingdom: Know that animals are multicellular heterotrophs. They are
eukaryotic and lack cell walls. All are capable of locomotion at some point in their life
cycle. Be able to describe the different kinds of body symmetry, the different kinds of
digestive systems and the different kinds of body support systems. Be able to identify the
unique characteristics of a chordate and of a mammal. Differentiate between
homeothermic and poikilothermic.
People: Know the following people and their contributions to science.
Gregor Mendel, Louis Pasteur, Francesco Redi, Charles Darwin, James Watson, Francis
Crick, Rosalind Franklin, Carolus Linneaus
Vocabulary: At a minimum, know all vocabulary Words of the Week. .(Both Quarters)
