Eukaryotic Cells vs. Prokaryotic Cells

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.

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.

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

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

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
