  1. Cell Structure and Function

  2. Scientists responsible for the tools and foundations of cell biology: Robert Hooke

  3. Scientists responsible for the tools and foundations of cell biology: Anton van Leeuwenhoek

  4. Scientists responsible for the tools and foundations of cell biology: Matthias Schleiden

  5. Scientists responsible for the tools and foundations of cell biology: Theodor Schwann

  6. Scientists responsible for the tools and foundations of cell biology: Robert Brown

  7. Scientists responsible for the tools and foundations of cell biology: Rudolf Virchow

  8. Cell Theory The work of these scientists provided information significant to the development of the cell theory All living organisms are alike because they are composed of cells … by studying the composition and chemistry of the cell, we understand the chemistry and composition of all kinds of life forms

  9. Cell Organelles – Their parts, structure, and function

  10. Cell parts come from molecules 4 Types of Organic Molecules: Nucleic Acids - - Carbohydrates - - Proteins - - Lipids - -

  11. Cell Membrane Function: - - - * - * *Transport Mechanisms

  12. Cell Membrane Phospholipid Bilayer … …fluid mosaic model = Proteins … … Carbohydrates … (cholesterol) …

  13. Nucleus Functions: - - = CHROMATIN - CHROMOSOMES

  14. Nucleus - - Nucleolus: - - , -

  15. Cell Fluids Plasm = Cyto = _________plasm: Inside of the nucleus _______plasm: Outside of the nucleus

  16. Cytoplasm Organelles in the cytoplasm of ______eukaryotic cells: Ribosomes Endoplasmic Reticulum Golgi Apparatus Lysosomes Cytoskeleton Vacuoles Mitochondria Organelles in _______eukaryotic cells: Choloroplasts Cell Wall Flagella Cilia Centrioles
