What is the nucleus?
The central part of the cell, which is enclosed in a membrane and is usually darker than the rest of the cell because it contains genetic material.

What are ribosomes?
Only visible with an electron microscope and appear as black bodies located on the rough ER, or lying free in the cytoplasm. They contain different forms of RNA and their role is to manufacture proteins, as instructed by the DNA in the nucleus.

Small vesicles produced by part of the Golgi apparatus. They can travel freely throughout the cell and, by releasing their contents they can destroy damaged organelles and even entire cells- this is because they contain powerful enzymes.
