  1. a motor protein that moves vesicles to the cells periphery
  2. b (1665)
    -Examined a thin slice of cork tissue
    -Observed honeycombed compartments he called cellulae
    -Term became cells
  3. c -proposes that mitochondria and chloroplasts arose by symbiosis from ancient bacteria
    -this theory is supported by a wealth of evidence
  4. d -a mixture of glycoproteins secreted by animal cells
    -helps coordinate the behavior of all cells in tissue

  3. -anchor and assmble microtubules
    -not found in plants or fungi
    -may have originated as symbiotic bacteria
  4. -Is associated with proteins
    -During cell division, condenses into chromosomes
    -After cell division, relaxes into chromatin
  5. -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
