Pre – AP Biology Types of Cells and Cell Structures Part 1 Henri Dutrochet Cell is the basic unit of life Theodor Schwann All animals are composed of cells Matthias Schleiden All plants are composed of cells Rudolf Virchow All cells come from pre-existing cells Robert Hooke His simple microscope Anton von Leeuwenhoek Compound microscope Anton’s Microscope Modern Light Microscopes Microscopic Resolution Different types of light microscopes Electron Microscope They can be very large and expensive Inside an electron microscope Images from an electron microscope Transmission (left)/Scanning (right) Prokaryotic Cell Structure Eukaryotic Cell (plant) Eukaryotic Cell (animal) Surface Area to Volume relationship Pre – AP Biology Types of Cells and Cell Structures Part 2 Nucleus Structure Chromatin vs. Chromosomes appearance within the cell. Ribosome Structure Pre – AP Biology Types of Cells and Cell Structures Part 3 Endoplasmic Reticulum Golgi Apparatus Lysosomes Central Vacuole of a plant Contractile Vacuole of aquatic single celled organisms Used to get rid of excess water so that the cell does not burst Endocytosis Mitochondrial Structure Notice the two different “spaces” Chloroplast Structure Notice the two different “spaces” Lynn Margulis Endosymbiont Hypothesis Pre – AP Biology Types of Cells and Cell Structures Part 4 Cytoskeleton Microtubules - Centrioles Microtubules – Cilia or Flagella Microfilaments used in various cells for movement Actin and Myosin in Muscle tissue Muscle Tissue under the Microscope Can you see the actin and myosin bands? Plant cell wall structure Extra-cellular matrix of animal cells Cellular junctions helping to make tissues from individual cells Cells from your lung tissues Junctions between plant cells Cells are the sum of it’s parts They need all parts to function properly
