The differences and similarities of Eukaryotic and Prokaryotic Cells

Introduction

Cells are the basic building blocks of life. Cells across all types of organisms can be fundamentally categorised into being either Euraryotic or Prokaryotic cells. Any organism usually only contains type of the given cells but not both. Prokaryotic are very simple cells that have existed since the dawn of life and are generally smaller than the more complex Eukaryotic cells. Bacteria are made up of one or more prokaryotic cells. While Eukaryotic cells are found inside plant and animal life. Eukaryotic cells are more advanced and larger.

History

Around 3.5 billion years ago life first began on earth in the form of very simplistic Prokaryotic cells. These evolved from microspheres that formed from out of a primordial soup that contained the ingredients of life. 3.5 billion years later these cells still exist today.

Then approximately 1.8 billion years ago Eukaryotic cells first evolved. This was a really big step in the evolution of life. Until this point, all organisms were bacteria that were prokaryotic (without a nucleus). It is thought that there were different types of these prokaryotic bacteria living together, one inside of
