    dead plant cells
  2. the smallest units of life ina ll lliving things are
    cells
  3. when the volume of a cell increases, its surface area,
    increases at a slower rate
  4. surface area is a n important factor in limiting cell growth because?
    the cell may become too large to take in enough food and to remove enough wastes.
  5. teh size to wicha cell can grow is limited by its
    surface area
  6. cell that can change its shape would be well suited for
    moving to diffferent tissues through narrow openings
  7. one difference between prokaryotes and eukaryotes is that
    prokaryotes have no nuclear membrane
  8. what is a charcteristic of prokaryotes?
    they existed on earth before eukaryotes
  9. which of the following is an example of prokaryotic cell?
    a bacterium
  10. only eukaryotic cells have
    membrane-bound organelles
  11. plasma membranes are?
    thing coverings that surrounded cells
  12. the structure that regulates what enters and leaves the cell is called the
    plasma membrane
  13. the plasma membrane
    encloses contents of a cell, allows material to enter and leave the cell, is selectively permeable.
  14. a structue within a cell that performs a specific functin is called an
    organnelle
  15. a particularly active cell might contain large numbers of
    minochondria
  16. the golgi apparatus is an organelle that
    labels the molecules made in the endoplasmic reticulum with tags that specify their destination, realses molecuels in vesicles, receives proteins and lipids form the endoplasmic reticulum.
  17. on importnat organelle that helps manintain homeostasis by moving supplies from one part of the cell to the other side is the
    endoplasmic retifulum
  18. where is ATP produced?
    mitochondrion
  19. numerous hairlike organelles that protrude form teh surface of a cell and are paacked in tight rows are called
    cilia
  20. proteins are made on the
    ribosomes
  21. the packaging and distribution center of the cell is the
    golgi apparatus
  22. the double membrane surrounding the nucleus is called the
    nuclear envelope
  23. cell: plasma membrane::
    nucleus: nuclear envelope
  24. all of the following are found in both plant and animal cells except?
    a cell wall
  25. how are chloroplasts like mitochondria?
    the both contain DNA.
  26. THE ORGANELLES ASSOCIATED WITH PHOTOSYNTHESIS ARE THE
    CHLOROPLASTS
  27. the organelles in plant cells that contain a green pigment are the
    chloroplasts
  28. plant cells have a large membrane bound space in wich water, waste products, and nutrients are stored. This place is known as a
    central vacuole
  29. which of the following pairs contains unrelated items?
    cell wall-animal cell
  30. plant cells..?
    have a cell wall instead of a plasma membrane.
  31. which of the following is the correct order of organizatin of structures inl iving things, from simplest to most complex?
    cells, tissues, organs, organ systems

    cell theory
  33. the ratio of surface area to _____ puts limitations ona cell's size
    volume
  34. eukaryotic cells are much larger and have more specialized functins than prokaryotic cells bcause they contain_____wich carry out speacialized activities.
    membrane bound
  35. a cell with a well-defined nucleus and cytoplasm suurrounded by a plasma membrane is an______cell
    eukaryotic
  36. a plasma membrane is said to be____ permeable becaue it allows the passage of some solutes and not others.
