The nucleus contains strands of DNA (chromosomes) in the form of a double helix. Within the human body there are cells that have no use for a nucleus such as red blood cells and cells that contain multiple nuclei such as muscles, because they are more active.

This organelle is found in most cells in the body and is also a packaging organelle. The Golgi apparatus looks very similar to the rough endoplasmic reticulum but have majorly different functions. The main function of the Golgi apparatus is to gather simple molecules and combine them with others to create more complex molecules, packages them in vesicles and either temporarily stores them for later use or send them to other cells. The Golgi apparatus is also responsible for transporting newly synthesised proteins.
Lysosome is found in all parts of the cytoplasm, which holds enzymes that were created by the cell. The purpose of this organelle is to digest unwanted substances. They can be used to digest food or break down the cell when it dies. Lysosome is able to digest all major chemicals because they contain powerful
