The part of a cell that separates the material outside the cell from the material inside the cell.
The “control center” of a cell.
A dense region of ribonucleic acid (RNA) in the cell’s control center, and the site of ribosome formation.
The gel-like fluid inside the cell that (1) is the medium for chemical reaction; and (2) provides a platform upon which other structures can operate within the cell.

The general name for the process by which new cells are formed for growth, repair, and replacement in the body.
The movement of particles (solutes) in a cell from a region of higher solute concentration to a region of lower solute concentration.
The diffusion of solvent or water molecules through a selectively permeable membrane.
A process that uses pressure to push substances through a membrane.
A process that moves substances against a concentration gradient from a region of lower concentration to a region of higher concentration, requiring a carrier molecule and using energy.
The formation of vesicles to transfer particles and droplets from outside to inside the cell.
The process of moving secretory vesicles from the inside to the outside of the cell.
The type of cell reproduction used by all cells except those that give rise to the gametes.
