• Red blood cells are also called Erythrocyte
• Diffusion does not require ATP
• Random movement due to intrinsic kinetic energy movement is down a concentration gradient (downhill)

  Diffusion
• Higher water concentration to one of lower water concentration

  Osmosis
• Osmosis exerts a pressure, termed osmotic pressure, which is the force required to prevent movement of water across cell membrane
• A cell immersed in an isotonic solution has the same solute concentrations inside and outside the cell.

  Isotonic
• A hypotonic solution has a lower concentration of solutes and a higher concentration of water relative to the cytoplasm of the cell.

  Hypotonic
• The cytoplasm of a cell in a hypertonic solution has a lower solute concentration and higher water concentration that the surrounding solution.

  Hypertonic
• Water moves by osmosis into the cell, causing it to swell

  Hypotonic
• A little nut that contains the dna of the cell

  Nucleus
• Sausage shaped,Supplies 95% of the atp required by the cell

  Mitochondria
• Vesicle packed with enzyme known as the digestive system of the cell

  Lysosomes
• Outermost boundary of the cell, regulating substances that enter and exit the cell

  Plasma Membrane
• Forms the framework or scaffold of the cell

  Cytoskeleton
• Saucer shaped for post translational modification of proteins

  Golgi Apparatus
• Nine triplets of microtubules facilitates movement of chromosomes during cell division

  Centriole
• What parts of the cell are involved in protein synthesis?

  • Rough endoplasmic reticulum
  • Nucleus
  • Golgi Apparatus
