“What is the fundamental part of biological organisms?”

 

Have you ever wondered what is the most fundamental part of biological organisms? Well, believe it or not, all living beings are primarily composed of a form of matter called cells. Cells are defined as the simplest form of living matter. There are two types of cells, eukaryotic and prokaryotic cells . Eukaryotic cells contain a true nucleus (which houses DNA), and is contained in cell membrane to isolate itself from other cells. Prokaryotic cells are different from  eukaryotic cells because instead of having the DNA isolated in a protective membrane, it is wrapped up in a region called the nucleoid. Complex life such as plants, animals, fungi, and protists are composed of eukaryotic cells, while simpler life is composed of prokaryotic cells.
