WebbEndocytosis ( endo = internal, cytosis = transport mechanism) is a general term for the various types of active transport that move particles into a cell by enclosing them in a vesicle made out of plasma membrane. There are variations of endocytosis, but all follow the same basic process.

Passive transport review (article) Khan Academy

Passive transport is a type of membrane transport that does not require energy to move substances across cell membranes. Instead of using cellular energy, like active transport, passive transport relies on the second law of thermodynamics to drive the movement of substances across cell membranes. Fundamentally, … Visa mer Diffusion is the net movement of material from an area of high concentration to an area with lower concentration. The difference of concentration between the two areas is often termed as the concentration gradient, … Visa mer Osmosis is the movement of water molecules across a selectively permeable membrane.
