1. Eukaryotic Cells vs. Prokaryotic Cells

2. Cell Theory Cells are the basic units of living organisms.
The cell theory states that:
All living things are made of one or more cells.
Cells are the basic unit of structure and function in living things.
All cells come from other cells.

3. Cell Types Two categories: 1. Cell that have membrane-bound organelles
Called Eukaryotic Cells
2. Cells that do not have membrane-bound organelles
called prokaryotic cells
Unicellular organisms such as bacteria are examples of prokaryotes.

4. Cell Types Eukaryotic cells-
Cells that contain organelles which are held together by membranes
Examples include plant and animal cells.

5. Eukaryotic Cell Structure
The plasma membrane/cell membrane
the flexible boundary of a cell
separates a cell from its surroundings

6. Plasma Membrane/Cell Membrane continued:
allows nutrients to enter the cell and waste to be removed
This is referred to as selective permeability. *(Selective=Chooses, Permeability=filter through)*
keeping a healthy balance of nutrients and water within the cell is called homeostasis
