  1. nucleolus
    contains ribosome and proteins, manufactures ribosome's
  2. sac-like structure that stores mainly water as well as minerals and fats
    vacuole
  3. centrioles
    structure used in cell division in mitosis
  4. Eukaryote
    this type of cell has a membrane bound nucleus as well as other membrane organelles
  5. Plastids
    this organelle stores pigment and food
  6. nucleus
    This organelle controls all cellular activity, refereed to as the control center of the cell
  7. flagella
    long whip-like structure used in cellular movement
  8. Gogi Complex
    Modifies, collects, packages, and distributes macromolecules within the cell, referred to as the UPS center
  9. Microfilament
    smallest cyoskeletal element, contributes to cell shape, growth and movement
  10. Cytoplasm
    fluid portion of the cell between the nucleus and cell membrane
  11. Chromoplast
    This organelle in plants is used for the storage of plant pigments other than green
  12. Cell membrane
    Porous outer covering of cell, monitors what enters or exits the cell
  13. Ribosomes
    where proteins are made, some are attached, some are free
  14. Prokaryote
    This type of cell has no membrane bound nucleus
  15. Mitochondria
    Releases energy in the form of ATP for cells to use, referred to as the POWERHOUSE of the cell
  16. Chloroplast
    Organelle necessary for photosynthesis to occur in plants, uses sunlight energy to make food
  17. Rough ER
    Processor and transporter of proteins through channels that are studded with ribosome's
  18. Smooth ER
    Processor of lipids and carbohydrates
  19. Lysosome
    Digests unwanted or harmful materials in the cell, Recycling Center of the cell
  20. Luekoplast
    Place in the plant cell where starch is stored
  21. place in the plant where starch is stored
    luekoplast
  22. cholorplasts
    organelle necessary for photosynthesis to occur in the plants, uses sunlight to make energy
  23. Mitochondria
    releases energy in the form of ATP for cells to use, referred to as the POWERHOUSE of the cell
  24. Microtubule
    largest cytoskeletal element, contributes to cell shape, growth and movement
  25. Cilia
    short thread-like structures used with cellular movement
  26. Porous outer covering of cell, monitors what enters and exits the cell
    nuclear membrane
  27. what is the lipid bilayer made up of
    phospholipids and proteins
  28. what 2 parts do phospholipids have
    • the polar head called hydrophilic which loves water
    • the non-polar tail called hydrophobic which don't like water
  29. In a lipid bilayer proteins are attached to what
    some with carbohydrates attached
  30. what is the function of the protein in a lipid bilayer
    - form channels and pumps to move material across the membrane
  31. what do carbs act as in a lipid bilayer
    act as chemical identification allowing for recognition of foreign cells by organisms
  32. define diffusion
    substances move from areas of high concentration to areas of low concentration
  33. can occur with solids, lipids and gases and no energy is used
    diffusion
  34. facilitated diffusion
    substances diffuse across the cell membrane through special protein channel
  35. proteins are specific to ions, sugars, and salts  and no energy is used by the cell
    faciliatated diffusion
  36. stiffness, rigidity of cells, amount of water present
    osmotic (turgor) pressure
  37. the more water in the cell, 
             cells become large and inflated (turgid)
    high osmotic pressure
  38. if water is lost in the cell, 
    cells become small and deflated 
    (plasmolysed)
    low osmotic pressure
  39. what is hypertonic solution
    the concentration of water inside the cell is greater than outside the cell; therefore the cell will shrink
  40. what 2 things happen in a hypertonic solution
    • cell will become dehydrated 
    • water will leave the cell (low turgid pressure)
  41. what is hypotonic solution
    the concentration of water outside of the cell is greater than inside the cell; therefore the cell will expand
  42. what 2 things happen in hypotonic
    • cell will become hydrated 
    • water will enter the cell
  43. what is isotonic solution
    the concentration of water outside of the cell is equal to the concentration of water inside the cell; therefore the water movement across the cell is equal
  44. 2 things that happen in active transport
    • goes across a gradient 
    • molecule is too big
  45. endocytosis
    process by which organisms bring larger material into the cell the membrane actually creates a pocket around the object to bring in
  46. phagocytosis
    cellular eating the cell membrane surrounds material and creates a food vacuole
  47. pinnocytosis
    cellular drinking creates a water vacuole
  48. what is exocytosis
    process by which organisms use energy to get rid of materials that is doesn't need
  49. what are the 10 organ systems
    • cardiovascular
    • respirtory 
    • digestive 
    • muscular 
    • nervous
    • skeletal
    • skin
    • reproductive
    • excretory
    • endocrine
