To Do • Print Quizzes • Print Sections 6.1, 6.2, 6.4, 6.5, 6.6 • Print Chapter 6 Review up to question #19
Agenda • Finish HW • Turn in HW • Quiz on Population • Lecture on Cells • Practice on Cells • Break • Reading/Work Time
30 Minutes Work/Reading Time • Finish Chapter 4 • Section 4.1: #1-6 • Section 4.2: #1-6 • Chapter 4 Assessment: #1-15 • Page 94 Graph (the five vocab words) • Predation & Competition • Density Dependent Factors • Density Independent Factors • Rates that affect population size • Why can’t a population grow indefinitely? • S Curve & J Curve (part of the graph)
Quiz • Population • Complete quiz silently • Keep eyes on your own work • Turn over when finished
Cells Cells Eukaryotic Prokaryotic • Single or Multicellular • True Nucleus • Complex • Single Cell • No Nucleus • Simple Bacteria Fungi • Early life • Found almost everywhere Archaea • Mostly multicellular • Rigid cell walls • Consume dead matter • Extreme conditions (salt, heat, no oxygen) Plant Protist • Multicellular • Photosynthesis for food • Rigid cell walls • Chloroplasts • Mostly unicellular • Don’t fit in, but plant-like, animal-like, or fungi-like Animal • Multicellular • Digest their food • Can move independently
Cells *Any cell part is called an “organelle” • Prokaryotic Cells (Bacteria, Archaea) Cytoplasm -Gel-like fluid Nucleoid (DNA) - NO membrane around DNA Ribosome - Makes proteins Pilus (pl. Pili) - Attach to other bacteria Capsule - Additional Protection Flagellum (pl. Flagella) - Movement Cell Wall - Rigid Shape • Plasma/Cell Membrane • Encloses cell • Regulates entrance & • exit of substances
Cells • Eukaryotic (Animal, Plant, Fungi, Protist) Centrioles -Organize cell during division Cytoplasm Vacuole (Animal) -Store food, water, waste & minerals (small) Ribosomes Plasma/Cell Membrane Peroxisome -Breaks down fatty acids Cytoskeleton -Structure & internal movement Rough Endoplasmic Reticulum -Transports & folds proteins Lysosome -Enzymes breakdown macromolecules Smooth Endoplasmic Reticulum -Lipid Synthesis Golgi Apparatus -Packages macromolecules to be shipped out of cell Mitochondrion (pl. Mitochondria) -Provides energy Flagellum (sometimes)
Cells • Zoom-In on Nucleus • Nucleus • Regulates all cell activity • Membrane bound • Contains DNA Nucleolus -Synthesizes ribosomes Nuclear Envelope -Encloses DNA • Nuclear Pore • Exchange materials
Cells • Eukaryotic (Animal, Plant, Fungi, Protist) Cell Wall -Rigid shape, prevents bursting from too much water Plasmodesmata -Transport & communication b/twn cells Cytoplasm Cytoskeleton Vacuole (Plant) -Store food, water, waste, & minerals (large) Chloroplast -Use sunlight to synthesize sugar (photosynthesis) Peroxisome Mitochondrion Nucleus -Nucleolus -Nuclear Pore -Nuclear Envelope -DNA Ribosomes Smooth ER Plasma/Cell Membrane Rough ER Golgi Apparatus
Practice • Redraw the diagrams without labels • Use these to study tonight
Reading/Work Time • Annotation: Sections 6.1, 6.2, 6.4, 6.5, 6.6 • Concept Checks for each Section • Chapter 6 Review • #1, 2, 4-10, 14-17, 19
