1 EOC Review

2 What to Review Genetics Cell Transport Cell Cycle Ecology & Behavior DNA Organic Molecules Cell Structure & Function Cellular Respiration Ecology & Pollution Classification Red = 5 or less got correct Orange = 6-10 got correct Yellow = got correct

3 Cell Structure and Function Differentiation Prokaryote vs Eukaryote Cell Structure Cell Organelles

4 Stem Cells Nerve Cells Blood Cells Brain Cells

5 Prokaryote: NO membrane bound organelles NO nucleus bacteria are an example Eukaryote: HAS membrane bound organelles HAS a nucleus plant and animal cells; found in most organisms

6 Flagella, cilia Ribosomes Cell membrane Cell wall Nucleoid Few internal structures Single cell Chloroplasts Centrioles Cytoskeleton Nucleus Nucleolus Vacuole Lysosome Golgi Apparatus Mitochondria

7 Cell Cycle Stages of the Cell Cycle Mitosis vs Meiosis Asexual vs Sexual Reproduction

10 Meiosis allows for genetic variation within organisms gametes (sex cells) to have half the number of chromosomes as the parent In asexual reproduction the offspring are genetically identical to the parent organism In sexual reproduction the offspring are genetically different from the parent organisms

11 DNA DNA coding for proteins Cell, protein and DNA relationship DNA structure and function DNA fingerprinting

16 Genetics Transgenic Organisms Genetic crosses Mutations

17 This type of genetic engineering can be used for many purposes -treating or curing certain diseases -treating genetic disorders -improve food crops

21 Ecology Natural Selection Animal Locomotion Animal Behavior

22 “organisms best suited to their environment reproduce more successfully than other organisms” 1. Adaptation 2. Competition *selection conditions change as the demands of the environment change *if change is too extreme and organism can’t change, they become extinct or die

23 Paramecium - cilia Euglena - flagellum Amoeba - pseudopod

25 Cellular Transport Active vs Passive Transport Homeostasis Hypotonic, Hypertonic, Isotonic

28 LESS solute outside the cell than inside. MORE water outside the cell than inside CELL SWELLS HYPOTONICISOTONIC SAME solute amount both inside and outside the cell. SAME water amount both inside and outside the cell. HOMEOSTASIS HYPERTONIC MORE solute outside the cell than inside. LESS water outside the cell than inside. CELL SHRINKS

29 CARBOHYDRATES LIPIDS PROTEINS NUCLEIC ACIDS Contain: CHO Building Blocks: monosaccharides disaccharides Polysaccharides Used: to provide energy to living organisms Examples: Mono- glucose, fructose, galactose Di- sucrose Poly- glycogen, chitin, starch, cellulose Contain: CHO Building Blocks: fatty acids arranged as triglycerides, phospholipids, wax; includes steriods Used: to provide protection, insulation and energy storage Examples: trilauroylglycerol; lecithin; cholesterol, testosterone Contain: CHON Building Blocks: amino acids – there are 20 different ones Used: to provide shape and support Examples: hormones, hemoglobin, insulin, enzymes Contain: CHON Building Blocks: nucleotides – adenine, guanine, cytosine, thymine, uracil Used: stores important information in the cell, codes for proteins Examples: DNA, RNA

30 Aerobic – uses oxygenAnaerobic – does NOT use oxygen Makes the most ATP (32-38) Makes only 2 ATP Includes lactic acid fermentation (muscles) and alcohol fermentation

31 Kingdom Animalia Animalia Animalia Phylum Chordata Chordata Cnidaria Class Mammalia Mammalia Hydrozoa Order Primates Primates Siphonophorae Family Hominidae Hominidae Physaliidae Genus Homo Pan Physalia Species sapiens troglodytes physalis HUMAN CHIMP PORTUGUESE MAN O’ WAR

32 Cladograms “uses derived characters to establish evolutionary relationships” Cladograms – diagram showing relationship among animals Derived characteristic * ex) Jaws, Lungs, Nails - everything to the right have jaws - everything to the left does not

33

34 Phylogenetic tree *evolutionary past * base of tree = common ancestor

35

36 Biotic Relationships Competition – when two organisms compete for the same thing Predation – when one organism uses another organism for food Symbiosis – when two organisms or different species live in close association with one another – parasitism, commensalism, mutualism, mimicry

37 Parasitism – one organism gets nutrients from a host organism – One benefits, one suffers Commensalism – one organism benefits, the other is neither helped or harmed – One benefits, one neutral Mutualism – both organisms benefit – Both benefit Mimicry – when a harmless species resembles a poisonous or distasteful one – Ex. Monarch and Viceroy butterflies; eastern coral snake and scarlet king snake

38 DNA to Proteins STEP 1: REPLICATION (make a copy) DNA to DNA STEP 2:TRANSCRIPTION (convert to mRNA) DNA to mRNA STEP 3:TRANSLATION (figure out the amino acid) mRNA to amino acid

39 DNA Replication -process where DNA makes a copy of itself (DNA  DNA) CCT TAC CCG AAA TAC GCA ACT TAC CTA TTA CGA TAG

40 Transcription mRNA is made from DNA in the nucleus Pairing Rules Replicated DNA mRNA Adenine  Uracil Thymine  Adenine Cytosine  Guanine Guanine  Cytosine

41 DNA TTA CGA CTA GGC GCT Comp. DNA mRNA DNA GGC TAT TCG GCA AAT Comp. DNA mRNA Practice

42 TRANSLATION  Making proteins from mRNA  Occurs in the cytoplasm at the ribosome

43 Practice DNA: AAT CTA GGT CGT ATG GGG mRNA: Translate:
