1. Parts of the Eukaryotic Cell Eukaryotic cells generally have three main components I.A cell membrane

2. Parts of the Eukaryotic Cell Eukaryotic cells generally have three main components I.A cell membrane II.A nucleus

3. Parts of the Eukaryotic Cell Eukaryotic cells generally have three main components I.A cell membrane II.A nucleus III. Other organelles

4. Cell Membrane The entire cell is surrounded by a thin membrane. Function: controls which substances pass into and out of the cell. SELECTIVELY PERMEABLE

5. Structure: composed of phospholipids and proteins in a double layer or bilayer. (Cell membrane continued)

6. Floating around in the cell membrane are different kinds of proteins. They are not held in any fixed pattern but instead float around in the phospholipid layer. This model is called the fluid mosaic model. The positions of the lipids and proteins is constantly changing. (Cell membrane continued)
