Definition
| Regulates all cell activity. It does this by controlling the enzymes. Stores all genetic information. |
|

Term
|
Definition
| Synthesize rRNA and ribosomal subunits. Are related to protein production. |
|
|
Term
| Endoplasmic Reticulum (ER) |
|
Definition
Two forms
Smooth ER
Rough ER (contains ribosomes)
Functions
Synthesis of organic molecules
Carbohydrates, Lipids, Protein (RER)
Transport within the cell storage |

|
Term
|
Definition
| Is important in the synthesis of lipids and membrane proteins. |
|
|
Term
|
Definition
| Has ribosomes and is the site of protein synthesis. |
|

Power house of the cell, is kidney shaped.
Uses ATP - requires O2 - spits out CO2 |
|
|
Term
|
Definition
A cellular "scaffolding" or "skeleton" contained within a cell's cytoplasm and is made out of protein.
The primary importance of the cytoskeleton is in cell motility. The internal movement of cell organelles, as well as cell locomotion and muscle fiber contraction could not take place without the cytoskeleton. |

Term
|
Definition
| The microvilli are tiny, hairlike structures on the surface of epithelial cells involved in absorption and secretion. |
|
|
Term
|
Definition
Associated with the cytoskeleton.
Centrioles form the spindle apparatus during cell division that is associated with the movement of DNA. Movers of chromosomes. |
|
|
Term
|
Definition
Small hair like extensions.
Cilia "beat" rhythmically to move fluids across the cell surface.
Found in the trachea and reproductive tract. |
