1. What are the main cell parts?

2. Three Main Cell Parts BOTH plant and animal cells have three main cell parts Each main part has a special and important job to do! The three main parts are: 1.Cell membrane (also called plasma membrane) 2. Cytoplasm 3. Nucleus

3. Cell Membrane Thin structure that surrounds the cell FUNCTION: Controls what goes in and out of the cell

4. Cell Membrane Rat neurons Cell membranes come in many different shapes: Human red blood cells Human heart muscle

5. Cytoplasm Gel-like substance inside the cell where most of the cell’s activities take place FUNCTION: Thick soup that cell parts swim in; also helps hold up cell shape

6. Cytoplasm Yeast cell Euglena

7. Nucleus Control center of the cell FUNCTION: Holds instructions for: 1. all cell jobs 2. making a new cell

8. Nucleus Human epithelial cellsHuman fibroblast
