What is the difference between a prokaryotic cell and a eukaryotic cell?
A
Prokaryotes do not have a nucleus or organelles, but a eukaryotic cell does
B
Eukaryotic cells do not have a nucleus or organelles, but prokaryotes do
C
Either A or B
D
None of the above
Explanation: 

Detailed explanation-1: -What is the difference between Prokaryotic and Eukaryotic cells? The defining characteristic feature that distinguishes between prokaryotic and eukaryotic cell is the nucleus. In prokaryotic cells, the true nucleus is absent, moreover, membrane-bound organelles are present only in eukaryotic cells.

Detailed explanation-2: -All cells have a plasma membrane, ribosomes, cytoplasm, and DNA. Prokaryotic cells lack a nucleus and membrane-bound structures. Eukaryotic cells have a nucleus and membrane-bound structures called organelles.

Detailed explanation-3: -Prokaryotes are always unicellular, while eukaryotes are often multi-celled organisms. Additionally, eukaryotic cells are more than 100 to 10, 000 times larger than prokaryotic cells and are much more complex. The DNA in eukaryotes is stored within the nucleus, while DNA is stored in the cytoplasm of prokaryotes.

Detailed explanation-4: -There are several differences between the two, but the biggest distinction between them is that eukaryotic cells have a distinct nucleus containing the cell’s genetic material, while prokaryotic cells don’t have a nucleus and have free-floating genetic material instead.

Detailed explanation-5: -DNA in eukaryotic cells is found inside the nucleus, while DNA in prokaryotic cells is located in the cytoplasm. Eukaryotic cells are generally larger and more complex than prokaryotic cells. Eukaryotic organisms include animals, plants, fungi, and paramecia. Prokaryotic organisms include bacteria and archaea.
