Answer:
Phospholipid bilayer
Explanation:
Liposomes are vesicles are spherical in shape. They consist of at least one phospholipd bilayer most especially phosphatidycholine. Liposomes are artficial vesicles similar to a membrane, because it has an hydrophilic core surrounded by a hydrophobic lipid bilayer.
Liposomes are artificial prepared and are used for the transportation of substances like drugs and nutrients between cell parts, outside of the cell and into the cell. Â
In liposomal drug delivery, the liposome fuses with other internal cell membranes at the site of action and releases its liposomal content.
