Cell parts and their functions

There are many things built out of cells, and each cell is made of smaller functions that are necessary for it to carry out its functions.

First is the cell membrane, which is the cell's outer wall and is what separates the insides of the cell from the outside environment. Inside the cell is the cell's Cytoplasm, a jelly-like substance that holds all its contents very rigidly.

Inside the Cytoplasm are something called Organelles, which are small, organ-like structures that can carry out their functions. If you look at cells, there are small bean-like organelles, which are mitochondria, which are the "powerhouse of the cell". These organelles break down sugar molecules to help power the cell.

The Nucleus is what holds all the genes of the cell, and sort of like computer code to the cell on what to do to survive or to reproduce.
