Bios 1063 Chapters 15/4 Part II -Eukaryotes-Cell Structure I I. Eukarytotic Cells have many structures called organelles (like small organs, each has a specific function). A. Plasma membrane -surrounds the cell-separates the inside from the outside of the cell. Controls what enters and leaves the cell. The cell membrane is composed of both phospholipids and proteins. Phospholipids are made of phosphate and 2 fatty acid tails. The phosphate heads are oriented inside and outside the cell with the fatty acid tails oriented together in the middle. There are 2 layers of lipids forming what we call the lipid bilayer. Proteins are embedded in the lipid bilayer. These proteins have many functions such as transport of nutrients into the cells (glucose to make ATP). For cells to recognize each other, and for ions to transport into the cell. The plasma membrane regulates what enters and leaves the cell. B. Cytoplasm
