Title: Cell Organization


1
Cell Organization
  • Section 7.2

2
I. Prokaryotic Cells
  • A. Have no membrane-bound organelles.
  • Have genetic material but no nucleus.
  • B. Include bacteria, fungi and algae.

3
II. Eukaryotic Cells
  • A. Have membrane-bound organelles.
  • B. Include animals and plants.

4
III. The Animal Cell
  • A. Eukaryotic cell.
  • B. Each cell has a different job to do.
  • C. Each cell works like a factory.

(Parts of the Animal Cell)
  • D. Cell Membrane
  • Flexible outer boundary of the cell.
  • Gate keeper of the cell.
  • Controls what enters exits the cell.
  • Selective permeability.
  • It is like the wall around Cell City.

7
  • E. Nucleus
  • Brain of the cell, it tells the other parts what
    to do contains DNA.
  • Mayor of Cell City.
  • Outer boundary is the nuclear envelope controls
    what enters/exits the nucleus.

8
  • - It contains chromatin, which is unraveled
    chromosomes (genetic material.)
  • - It has a nucleolus, a sphere-shaped object
    that helps make proteins.

9
  • F. Cytoplasm
  • Gel that fills the space between the cell
    membrane and the nucleus.
  • It holds all the organelles.

10
  • G. Endoplasmic Reticulum (ER)
  • Folded membrane that extends from the nucleus out
    to the cell membrane.
  • Transport system for moving materials around the
    cell.
  • The freeway in Cell City.
  • Rough ER contains ribosomes.
  • Smooth ER produces stores lipids.

11
  • H. Ribosomes
  • Make protein.
  • Construction sites in Cell City.
  • They are found on the surface of the Rough ER, or
    may be free-floating in the cytoplasm.

12
  • I. Golgi Bodies
  • Stacks of membranes that package and move
    proteins to the outside of the cell.
  • The U.P.S. of Cell City. They ship receive.

13
  • J. Mitochondria
  • Bean-shaped structures with an outer folded
    inner membrane.
  • Provide the cell with energy.
  • The powerhouses of Cell City.

14
  • K. Lysosomes
  • Digest waste and worn-out cell parts and remove
    them from the cell.
  • Garbage collectors of Cell City.

15
  • L. Vacuoles
  • Fluid-filled temporary storage sites in the cell.
  • Store materials, waste, food water.
  • Plant cells have one large vacuole animal cells
    have many small ones.
  • Warehouses or storage units of Cell City.

16
IV. The Plant Cell
  • 2 main differences from the animal cell
  • Cell wall
  • - rigid structure outside the cell membrane that
    supports protects the plant cell.
  • Chloroplasts
  • - light energy is changed into chemical energy
    in the form of sugar (and releases oxygen for us).
