WebFeb 25, 2024 · The primary function of the plasma membrane is to protect the cell from its surroundings. Composed of a phospholipid bilayer with embedded proteins, the plasma membrane is selectively permeable to ions and organic molecules and regulates the movement of substances in and out of cells. WebWhat is a phospholipid? Type of lipid made from 2 fatty acid chain “tails” attached to a phosphate group “head”. Describe the phospholipid’s polar nature and how it interacts with water. Phosphate head group is polar and hydrophilic. Fatty acid chains tail is non-polar and hydrophobic. Thus, heads face water and tails point inwards ...
