Unit One Building a Cell Project

List of the parts of the cell by the numbers on the cell model.
1) Cell Membrane: The outer surface of a cell that controls molecules entrance and exit.
2) Nucleus With Nuclear Membrane: Two membranes that enclose a flattened sac and are connected at the nucleor pore. It is enmeshed in a group of filaments for strength.
Endoplasmic reticulum: A complex network of membrane enclosed spaces
3) Rough ER: bordered by ribosomes that contain large amounts of RNA.
4) Smooth ER: These membranes smooth because they have no ribosomes.
5) Golgi Apparatus: consists of a stack of flat baglike structures which store and eventually release various products from the cell.
6) Lysosomes and Vesicles: small, round bodies containing many different enzymes. They break down many substances. For example they help white blood cells break down harmful bacteria.
7) Mitochondria: The power producers of the cell which are sausage-shaped structures. They produce almost all the energy the cell needs to live and do its work.
8)Cilia or Flagella Made of Microtubules: cylinders of protein molecules and they function to determine cell shape and variety of cell movements.
Conclusion: My model shows all the parts within a cell. By creating all the different parts by using things around the house gave me a good understanding of what the cell parts look like. I also have a better understanding of their function.

nice model...
its hard for me to remember all the structure and function...
good work...
