Chapter 8 Test Review Outline Write this information in your notes composition notebook
Section 8.1 5 scientists Hooke Leeuwenhoek Schleiden Schwann Virchow
Section 8.1 CELL THEORY All living things are composed of cells Cells are the basic units of structure and function in living things New cells are produced from existing cells
Section 8.1 Microscopes Light Electron SEM TEM
Section 8.1 PROKARYOTES EUKARYOTES NO nucleus NO membrane-bound organelles Small and simple Ex. Bacteria Nucleus Membrane-bound organelles Larger and more complex Ex. Plants, animals, fungi, protists
Section 8.2 ANIMAL CELLS PLANT CELLS Centrioles help organize cell division **Animal cells do have small vacuoles **Some have contractile vacuoles Cell wall Protection and support; water pressure Chloroplasts Photosynthesis Large central vacuole Water storage
Section 8.2 ORGANELLES Structure and function (what they look like and what they do) Study your organelle chart Remember to look at your extra notes for Section 8.2 (microfilaments, microtubules, etc.)
Section 8.2 Chromatin- granular material made of DNA and protein Chromosomes- threadlike form of DNA seen only during cell division
Section 8.3 Structure and Function Cell membrane (make sure you know all components of the cell membrane…carbs, proteins, etc.) Cell wall Concentration = mass solute/volume solution Equilibrium
Section 8.3 PASSIVE TRANSPORT Diffusion Osmosis Facilitated diffusion High Low Does NOT use energy Happens because molecules are always in motion Diffusion Osmosis Facilitated diffusion
Section 8.3 OSMOSIS Hypertonic Isotonic Hypotonic
Section 8.3 ACTIVE TRANSPORT Endocytosis Exocytosis Low high DOES use energy Use a protein pump Endocytosis Phagocytosis Pinocytosis Exocytosis
Section 8.4 Unicellular vs. multicellular Cell specialization Cells tissues organs organ systems Receptors
Section 8.4 4 types of tissues Muscle Epithelial Nervous Connective
Section 8.4 Some examples of specialized cells Red blood cell Pancreatic cell Muscle cell Cells in plant leaves
