Book: 4 edition Biological Science - Freeman Chapter 1: Text: Figures 1.2, 1.3, 1.4, 1.5 In Section 1.5 you are responsible for “The Nature of Science” and from the Null hypothesis through “Important Characteristics of Good Experimental Design”. You are not responsible for Scientific Names in Section 1.4 or the two experiments in Section 1.5. -Blue Thread and Check Your Understanding - Pasteur’s experiment (fig 1.2), end of Section 1.3, gene DNA sequences to determine diversity (fig 1.4), prokaryote and eukaryote cell size (fig 1.6), and end of Section 1.4 -Summary of Key Concepts - 1-5, of 5, including Blue Thread questions -Test Your Knowledge-questions 1-5 -Test Your Understanding -questions 1, 2, 5, 6 -Applying Concepts to New Situations -question 1-4 -Vocabulary: artificial selection inherited traits (heritable) cell natural selection cell theory null hypothesis conclusion phylogeny control(s) population domain prediction energy prokaryotic cell eukaryotic cell replication (properties of life) evolution results fitness species hypothesis tree of life information processing variation, genetic Chapter 7: Inside the cell Text: -Figures 7.1, 7.3, 7.5, 7.6, 7.21. Summary tables: 7.1 (How do the structures of Prokaryotes and Eukaryotes differ) and 7.2 (Eukaryotic Cell Components) -Sections 7.1-7.3. You are not responsible for figures 7.14, 7.15 or the accompanying text. You are also not responsible for “The Dynamic Cell” in Section 7.3 (although there are some very interesting facts that you might be interested in). -Blue Thread and Check Your Understanding -end of Section 7.2 and Fig 7.21 -Summary of Key Concepts -Key 1 (of 4 total) -Test Your Knowledge-question 1 -Test Your Understanding -question 1 1 -Vocabulary: cell wall mitochondrion centrioles morphology chloroplast nuclear envelope chromosome nucleoid cilium nucleus cytoplasm organelle cytoskeleton peroxisome cytosol photosynthetic membranes DNA plasma membrane endomembrane system plasmid endoplasmic reticulum (ER) ribosome flagellum rough ER gene smooth endoplasmic reticulum (smooth ER) Golgi apparatus vacuole lysosome 2 BIO 151 WEEK 1 NOTES Lecture 1: CELLS AND BIODIVERSITY Objectives: 1. Cell theory 2. Properties of life 3. Compare prokaryotic and eukaryote cells 4. Evolutionary principles CELL THEORY What are the 2 tenets of the cell theory? i. All living things are made up of cells ii. All cells arise from preexisting cells Relevant to evolution and properties of life Properties of life – what does it mean to be living/ how are you different from a rock?) 1. Reproduce self 2. Metabolism a. Take in carbon and generate energy to synthesize the things that maintain you (lipids, proteins, nucleic acid, carbs) 3. Process info for reproduction and energy 4. Made of cells (smallest unit of life) PROKS VS EUKS In the simplest case- a cell is a single compartment Prok- o no membrane around nucleus o DNA compacted within cell Euk- o multiple components o has membrane around nucleus o (10x in diameter than prok) Endomembranes= create separate compartments within the cell’s cytoplasm All cells have in common : mitochondria, cytoplasm, plasma membrane, cytosol, ribosomes (needed to make protein-> DNA) , nucleus Prokaryotes: Plant: cell wall, vacuoles, chloroplast animal cells : ribosomes, ER (rough and smooth), lysosomes, , golgi apparatus, EVOLUTIONARY PRINCIPLES Cells + evolution biodiversity Evolution Is a process o Species are related to each other through common ancestors o Species can change Evolution explains HOW change in a population occurs over time o Natural selection Requires heritable characteristics/ genes Requires different versions of genes/characteristics to have different outcomes for reproduction, survival, etc o Genetic variation + environmental influences NEW species How do we measure diversity? Morphology- visual exam, microscopy Gene sequence of shared components (ex: ribosomes- RNA + protein) o DNA: Chemistry, structure, function Mutation (can play into evolution) Metabolism o Obtaining carbon/ carbon intake Photosynthesis (plants/ autotrophs) Ingestion (need to eat) o Generate energy (ATP) Chemical thermodynamics Cellular respiration
