Considered the cell’s mailroom. It receives proteins and other materials from the endoplasmic reticulum, packages them, and distributes them to other parts of the cell.

Gel-like substance between cell membrane and nucleus that holds the organelles
Membrane that protects the nucleus. Contains pores that materials can pass in and out of.
The rigid outermost layer of a plant cell, which is made of cellulose. It helps to protect and support the cell.
The mass of like cells in an animal or plant body that form a specific organ.
