Summary Introduction
Introduction:
The organisms are classified into two types. These are prokaryotes and eukaryotes. Prokaryotes are the organisms that do not contain a well-defined nucleus. However, eukaryotes have a well-defined nucleus properly enclosed in a nuclear membrane. There are different types of
