Cells Parts

| **%%Part%%** | **%%Function%%** |
|----|----|
| Cell Membrane | Semipermeable covering to the cell. Made of a phospholipid bilayer. |
| Cytoskeleton | Made out of protein filaments. Helps give the cell structure. |
| Nucleus | Membrane-bounded region that houses genetic material. There are pores that allow RNA to leave the nucleus. |
| Nucleolus | A structure in the nucleus that makes ribosomes |
| Chromatin | Genetic material that condenses during cell division into chromosomes |
| Ribosomes | Organelles made of ribosomal RNA that are involved in protein synthesis.  Located on the Rough ER or floating within the cytoplasm. |
| Rough ER | Has ribosomes to synthesize proteins and lipids.  Proteins made by the rough ER will go to the Smooth ER for further modification.  The proteins travel by vesicles |
| Smooth ER | Further modifies proteins that come from the Rough ER.  No ribosomes are present.  The proteins travel by vesicles to the Golgi Body. |
| Golgi Body | Flattened sacs that package proteins that came from the Smooth ER to be exported out of the cell.  Vesicles will transport proteins out of the cell. |
| Mitochondria | Converts food energy into cellular energy (ATP) through a process called respiration |
| Lysosome | Collects and breaks down cellular debris.  Has hydrolytic enzymes.  |
| Centrioles | Helps in cellular division by organizing microtubule proteins into a spindle |
