Summary Introduction
Introduction:
The organisms that contain a well-defined nucleus are known as eukaryotic organisms. However, the group of organisms that lack a well-defined nucleus properly enclosed by a nuclear membrane are called prokaryotes. However, the eukaryotes are further classified into two major categories, plant cell, and animal cell.
