GENERAL HISTOLOGY

Detailed explanation-1: -Both eukaryotic and prokaryotic cells have a well defined nucleus.

Detailed explanation-2: -The primary difference between prokaryotic and eukaryotic cells is that a nucleus and other membrane-bound organelles are only present in eukaryotic cells.

Detailed explanation-3: -Prokaryotes are organisms whose cells lack a nucleus and other organelles. Prokaryotes are divided into two distinct groups: the bacteria and the archaea, which scientists believe have unique evolutionary lineages. Most prokaryotes are small, single-celled organisms that have a relatively simple structure.

Detailed explanation-4: -Eukaryotes are organisms whose cells contain a nucleus and other membrane-bound organelles. There is a wide range of eukaryotic organisms, including all animals, plants, fungi, and protists, as well as most algae. Eukaryotes may be either single-celled or multicellular.

Detailed explanation-5: -These cells do not have membrane-bound cell organelles such as Golgi bodies, mitochondria, lysosomes, ER, peroxisomes, etc. Prokaryotes do not have a nucleus, so hence do not have a nucleolus.
