5 Written questions

5 Matching questions

  1. Matthias Schledeiden, Theodor Schwann, Virchow
  2. vacuoles
  3. golgi complex
  4. centrioles
  5. Cell Theory
  1. a -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
  2. b -in plants-store dissolved substances and can increase the cells surface area
    -in protists-contractile vacuoles are used to pump excess water
  3. c Schledeinden (botanist)
    Schwann (zoologist)
    Virchow (put theory together)
    -Proposed the first 2 statements of the cell theory in 1838-39
  4. d -All organisms are composed of one or more cells
    -Cells are the smallest living things
    -Cells arise only by division of a preiviously existing cell
  5. e -anchor and assmble microtubules
    -not found in plants or fungi
    -may have originated as symbiotic bacteria

5 Multiple choice questions

  1. -Encases all living things
    -Its basic structure is represented by the fluid-mosaic model
    -Phospholipid bilayer with embedded proteins
    -In water, phospholipids spontaneously form a bilayer
    - Cell membranes contain zones called lipid rafts which are heavily enriched in cholesterol
  2. -proposes that mitochondria and chloroplasts arose by symbiosis from ancient bacteria
    -this theory is supported by a wealth of evidence
  3. -Is associated with proteins
    -During cell division, condenses into chromosomes
    -After cell division, relaxes into chromatin
  4. -found in almost all eukaryotes
    -powerhouses of cell
    -extract energy from organic molecules through oxidative metabolism
    -sausage shaped organelles, about the size of a bacterial cell
    -like bacteria, they possess circular DNA and divide by simple fission
  5. -found only in plants and algae
    -energy capturing centers
    - site of photosynthesis in plants and algae
    -like bacteria, they possess circular DNA and divide by simple fission
    -like mitochondria, they are surrounded by 2 membranes
    -inner membrane is more complex

5 True/False questions

  1. Cell Size-Cells range in size from a few micrometers to several centimeters
    -Most cells are small because larger cells do not function efficiently
    -It's advantageous to have a large surface-to-volume ratio
    -As cell size increases, volume grows much faster than surface area

          

  2. Endoplasmic Recticulum-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

          

  3. lysosomes-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

          

  4. cell movement-Cells range in size from a few micrometers to several centimeters
    -Most cells are small because larger cells do not function efficiently
    -It's advantageous to have a large surface-to-volume ratio
    -As cell size increases, volume grows much faster than surface area

          

  5. Prokaryotes-Include bacteria and archaea
    -Over 5,000 species are recognized
    -3 main shapes: rod, spiral, and spherical
    -Lack nucleus and organelles
