Liposome: 

• Consists of a bilayer of amphipathic molecules with both molecule layers arranged in concentric circles
• Is formed mainly by phospholipid molecules such as cholesterol 
• Structurally, the lipid bilayer separates an aqueous internal compartment
• Formation of liposome typically takes place at transition temperature

Micelle:

• Consists of lipid molecules arranged in a spherical form in aqueous solution
• Structurally, the lipid monolayers are closed, with a polar surface and fatty acid core
• Is formed by surfactant molecules such as emulsifiers and detergents
• Formation of micelle requires Kraft temperature as its minimum temperature value
