5 Matching questions

  1. flagella
  2. Endoplasmic Recticulum
  3. golgi complex
  4. DNA
  5. extracellular matrix
  1. a long and few in number
  2. b -a mixture of glycoproteins secreted by animal cells
    -helps coordinate the behavior of all cells in tissue
  3. c -internal membrane system creating channels and membrane bound organelles
    -consists of 2 regions: Smooth ER-embedded with enzymes and involved with lipid and carbohydrate systhesis
    -rough ER-studded with ribosomes and involved with protein
  4. d -flattened stack of membranes that are scattered throughout the cytoplasm
    -depending on cell, number of golgi bodies range from a few to several hundred--referred to as the golgi complex
    -golgi complex collects, packages, modifies, and distributes molecules
  5. e -Is associated with proteins
    -During cell division, condenses into chromosomes
    -After cell division, relaxes into chromatin

5 Multiple choice questions

  1. -Include bacteria and archaea
    -Over 5,000 species are recognized
    -3 main shapes: rod, spiral, and spherical
    -Lack nucleus and organelles
  2. motor protein that moves vesicles to the cells periphery
  3. -all cell motion is tied to movement of microfilaments and microtubules
    -changes in shape of microfilaments: enables some cells to change shape quickly, allow some cells to crawl and animal cells to divide
  4. -arise from the golgi complex
    -contain enzymes that break down macromolecules
    -function in intracellular digestion of worn out cellular components and substances taken into cells
    -resulting material is recycled
  5. -anchor and assmble microtubules
    -not found in plants or fungi
    -may have originated as symbiotic bacteria

  2. The Prokaryotic Membrane-There are two major kinds of cells: prokaryotes and eukaryotes

          

  3. cell walls-offer protection and support
    -fungal cell walls are made of chitin
    -plant cell walls are made of cellulose

          

  4. mitochondriamotor protein that moves vesicles to the cells periphery

          

  5. Matthias Schledeiden, Theodor Schwann, VirchowSchledeinden (botanist)
    Schwann (zoologist)
    Virchow (put theory together)
