Flexible and allows a unicellular to move.

Main Function:
* Homeostatis, balanced internal condition.
* Protective barrier
* Regulates transport (selectively permeable)
* Allows cell recognition
* Provide anchoring sites for filaments of cytoskeletons
* Providing binding site for enzymes
* Interlocking surface, binds cells together
* Contains in the cytoplasm

Membrane Components:
* Make up the cell membrane
* Lipid soluble molecules such as H2O, O2, and CO2. Semi-permeable

* Bilayer, which contains 2 fatty acid chains that are nonpolar (head is polar and contains a-PO4 group + glycerol, while the tail is nonpolar)

* Fluid Mosiac Model- individual phospholipids and prot...
