    dead plant cells
  2. The smallest units of life in all living things are
  3. When the volume of a cell increases, its surface area,
    increases at a slower rate
  4. Surface area is an important factor in limiting cell growth because?
    the cell may become too large to take in enough food and to remove enough wastes.
  5. The size to which a cell can grow is limited by its
    surface area
  6. A cell that can change its shape would be well suited for
    moving to different tissues through narrow openings
  7. one difference between prokaryotes and eukaryotes is that
    prokaryotes have no nuclear membrane
  8. what is a characteristic of prokaryotes?
    they existed on earth before eukaryotes
  9. only eukaryotic cells have
    membrane-bound organelles
  10. Studying a picture of a cell taken with an electron microscope, you find that the cell has no nucleus and no mitochondria, but it does have a plasma membrane and a cell wall. You conclude that the cell is probably from a(n)
  11. plasma membranes are?
    thin coverings that surround 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 structure within a cell that performs a specific function is called an
  15. A particularly active cell might contain large numbers of
  16. The Golgi apparatus is an organelle that
    labels the molecules made in the endoplasmic reticulum with tags that specify their destination, releases molecules in vesicles, receives proteins and lipids form the endoplasmic reticulum.
  17. One important organelle that helps maintain homeostasis by moving supplies from one part of the cell to the other side is the
    endoplasmic reticulum
  18. In which organelle is ATP produced?
  19. Numerous hair like organelles that protrude from the surface of a cell and are packed in tight rows are called
  20. Proteins are made on the
  21. The double membrane surrounding the nucleus is called the
    nuclear envelope
  22. All cells have:
    A covering called a plasma membrane that surrounds the cell and controls what information and materials enter and leave it, an internal fluid that gives shape to the cell and supports the other things within it, either a central zone or a nucleus that contains the cell’s genes.
  23. cell: plasma membrane::
    nucleus: nuclear envelope

    • How are chloroplasts like mitochondria?
    • the both contain DNA.
  24. The organelles associated with photosynthesis are
    The chloroplasts
  25. The organelles in plant cells that contain a green pigment are the
  26. Plant cells have a large membrane bound space in which water, waste products, and nutrients are stored. This place is known as a
    central vacuole
  27. Which of the following pairs contains unrelated items?
    cell wall-animal cell
  28. plant cells..?
    have chloroplasts and a cell wall
