Question

Which cell structures are seen in prokaryotic and eukaryotic cells?

Answer 1

DNA is found in the cytoplasm of a prokaryotic cell, but is not found in the cytoplasm of a eukaryotic cell.

Further explanation

Eukaryotes are organisms whose cells have a nucleus enclosed within membranes. All protists, fungi, plants and animals such as yeasts, fungi, Protozoa and Plant cells are examples of eukaryotes. While prokaryote is a unicellular organism that lacks a membrane-bound nucleus, or any other membrane-bound organelle. Bacteria and blue-green algae are examples of prokaryotic cells.

Prokaryotic DNA is found in a central part of the cell called the nucleoid. Whereas in eukaryotic cells, DNA is located in the nucleus, the mitochondria and the chloroplasts.

The distinction between DNA in prokaryotic cell and eukaryotic cell is that eukaryotic cells have a "true" nucleus containing their DNA, whereas prokaryotic cells do not have a nucleus.

Prokaryotic cells are quite simple in structure because they have no nucleus, no organelles and a small amount of DNA in the form of a single, circular chromosome. Whereas the eukaryotic cells have a nucleus, multiple organelles and more DNA arranged in multiple and linear chromosomes.

Answer 2

Answer:

Cell membranes, DNA, ribosomes and cytoplasm.

Explanation:

Prokaryotic cells are cells without a nucleus and membrane bound organelles.  

Eukaryotic cells are cells with a nucleus and membrane bound organelles, like mitchondria or endoplasmic reticulum.

Both have cell membranes that surround the cell. Both have DNA. In prokayotic the DNA is in a part of the cell called a nucleoid. In eurkaryotic, it is held in the nucleus. Both have ribosomes that make proteins, however prokaryotic cells have fewer. Both have cytoplasm as well.

Therefore, both prokaryotic and eukaryotic cells have cell membranes, DNA, ribosomes and cytoplasm.
