Definitions:

Osmotic Pressure

The pressure required to prevent the flow of solvent into a solution through a semipermeable membrane, driven by differences in solute concentration.

Receptor-Mediated Endocytosis

A cellular process by which cells absorb metabolites, hormones, proteins – and in some cases viruses – by the inward budding of plasma membrane vesicles containing proteins with receptor sites specific to the molecules being absorbed.

Hypotonic

Describes a solution with a lower concentration of solutes compared to another solution, leading to the movement of water into the cell.

Isotonic

A term used to describe a solution that has the same solute concentration as another solution, resulting in no net movement of water across a semipermeable membrane.
