What is Prokaryotic Cell or Prokaryotes?
Prokaryotes are single-celled organisms that are the earliest and most primitive forms of life in the earth. These cells are cells are which have not any true nucleus.
What are Eukaryotic cells or Eukaryotes?
Eukaryotic cells are cells that contain a nucleus and organelles and enclosed by a plasma membrane. Organisms that have Eukaryotic cells include Protozoa, fungi, plant and animals.
Here, the differences between Prokaryotic cells and Eukaryotic cells are given below.
