Cell Biology & Genetics Unit Outline

Big Idea: All living things are made of cells that have

specialized organelles used for maintaining and replicating

their own blueprints for life functions and adaptations.Unit Outline: Cell biology w/ Diffusion & Osmosis Central Dogma

Cell Biology

Cell Biology Standard 1: Identify the fundamental life processes of plants and animals

depend on a variety of chemical reactions that occur in specialized areas of the organism'scells.

Learn for mastery: Students will be able to

know thatcells are enclosed within semi-permeable membranes that regulatetheir interaction with their surroundings.know thatenzymes are proteins that catalyze biochemical reactions without

altering the reaction equilibrium and the activities of enzymes depend on the

temperature, ionic conditions, and the pH of the surroundings.

knowhow prokaryotic cells, eukaryotic cells (including those from plants andanimals), and viruses differ in complexity and general structure.

knowthe role of the endoplasmic reticulum and Golgi apparatus in the

secretion of proteins.

Test #1: Cell biology w/ Diffusion & Osmosis

Topic: Cell organelles and their functions (Chapter 7 study guide pg. 196)

Key Vocabulary =

7.1 cell, nucleus, cell theory, prokaryotes19.1 bacteria

19.2 virus

7.2 eukaryotes, endoplasmic reticulum, golgi apparatus, ribosome,

chromosome7.3 lipid bi-layer, diffusion, facilitated diffusion, active transport, osmosis

Key Concepts =

7.1 characteristics of prokaryotes and eukaryotes19.1 how bacteria is a prokaryote

19.2 structure of a virus, how viruses cause infections7.2 functions of major cell structures (focus on golgi apparatus, ER, and

nucleus)

7.3 main functions of cell membrane and cell wall, what happens during

diffusion, what osmosis is

Genetics Standard 4: The genetic composition of cells can be altered by incorporation of

exogenous DNA into the cells.

Learn for mastery: Students will be able toknowthe general structures and functions of DNA, RNA, and protein.

knowhow to apply base-pairing rules to explain precise copying of DNAduring semiconservative replication and transcription of information from DNA

into mRNA. knowhow genetic engineering (biotechnology) is used to producenovel biomedical and agricultural products.

Genetics Standard 3: Genes are a set of instructions encoded in the DNA sequence of

each organism that specify the sequence of amino acids in proteins characteristic of that

organism.

Learn for mastery: Students will be able to

a. Students know the general pathway by which ribosomes synthesize proteins,using tRNAs to translate genetic information in mRNA.

b. Students know how to apply the genetic coding rules to predict the sequence of

amino acids from a sequence of codons in RNA.

c. Students know how mutations in the DNA sequence of a gene may or may not

affect the expression of the gene or the sequence of amino acids in an encoded

protein.

d. Students know specialization of cells in multicellular organisms is usually due

to different patterns of gene expression rather than to differences of the genesthemselves.

e. Students knowproteins can differ from one another in the number and sequence

of amino acids.
