## Definition

the thick, jelly-like substance inside a cell that holds all the parts together. It is where most of the cell's chemical reactions happen.

For teachers: the semifluid substance within a cell, excluding the nucleus, in which organelles are suspended. It serves as the medium for various metabolic processes and provides structural support to the cell.

## Examples

- The cytoplasm fills the space inside the cell membrane.
- During cell division, the cytoplasm divides to ensure each new daughter cell receives the necessary organelles and nutrients.
- The cytoplasm is not a static environment; it is a dynamic matrix where the constant movement of vesicles and the cytoskeleton facilitates intracellular transport and communication.
