Detailed explanation-1: -Endocytosis is a form of active transport.

Detailed explanation-2: -Both endocytosis and exocytosis are active transport processes.

Detailed explanation-3: -There are three main types of passive transport: Simple diffusion – movement of small or lipophilic molecules (e.g. O2, CO2, etc.) Osmosis – movement of water molecules (dependent on solute concentrations) Facilitated diffusion – movement of large or charged molecules via membrane proteins (e.g. ions, sucrose, etc.)

Detailed explanation-4: -Endocytosis (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.
