Cell Membrane
 The outer “wall”
 Thin layer of lipids
 Imbedded in this lipid layer are
specialized protein “doors”
 Enter raw material
 Exit as finished or waste products

Cell Membrane
 Hydrophilic
circles with
hydrophobic
tails.
Cell Membrane
 Tails always 'push' away from the
water
 Causes the bi-layer.

 Suspends the intracellular
organelles.

Nucleus
 The “Office” of the Cell
 Controls the function of the cells
 Inside the Nucleus
 Chromosomes
 Genes
 DNA
 Controls Inheritance

Ribosomes
 New proteins are manufactured

Endoplasmic Reticulum
 The Transport and Communication
organelle
 Network of membranes the connect
the cell membrane to the nucleus
http://www.cbc.umn.edu/
Golgi Bodies
 The packaging and delivery
department
 Products (proteins) go through a final
assembly and packaging
http://www.cbc.umn.edu/
Mitochondria
 Powerhouse Organelle
 Manufacture ATP
 ATP is used as a source of energy for
the cell.

Lysosomes
 Garbage Disposal
 Digestion of unwanted proteins

Vacuole
 Look like holes in Swiss cheese
 Empty spaces within the cell
 Often contain products to be removed
from the cell.
