Cells are of two types on the basis of the composition of the nucleus- Prokaryotic and Eukaryotic.
Prokaryotic cell – Nuclear membrane is absent around the nucleus of this type of cells. These cells lack many important cell organelles such as Chloroplasts, Lysosomes, Golgi and Mitochondria. These types of cells are found in bacteria, viruses, bacteriophages and blue-green algae.
Eukaryotic cell– Fully developed Nuclear Membrane is found around the nucleus of this type of cells. All cell organelles are found in it. Its cell wall is made of fully developed Cellulose.
