What is a Nucleus?
In a eukaryotic cell, a membrane bound organelle that contains the cells DNA and that has a role in processes such as growth, metabolism, and reproduction.

What is ribosome?
Cell organelle composed of RNA and protein, the site of protein synthesis.
What is lysosome?
A cell organelle that contains digestive enzymes.
What is vacuole?
