Final answer:
Liposomes are small, spherical compartments made up of a lipid bilayer. They behave like cells and can be designed for specific functions, such as drug delivery. Liposomes play important roles in biology for organizing molecules in cells.
Step-by-step explanation:
A liposome is a small, spherical compartment made up of a lipid bilayer. These structures can be formed in the laboratory and behave similar to cells, forming a pellet when centrifuged. Liposomes can be custom designed using different types of phospholipids and proteins. They can be used for drug delivery to specific cells and tissues. Liposomes are important tools in biology for organizing metabolism, transport, and storage of molecules.
