Answer:

Prokaryotes are unicellular organisms that have a cell wall that surrounds the plasma membrane and gives the organism shape. It also does not have a membrane-bound nucleus to hold its chromosomes. The chromosomes of a prokaryote is found in a nucleoid, which is a part of the cytoplasm.

Hope this helps, have a wonderful day/night, stay safe, happy holidays, and merry christmas!

Hey there!

Your answer is B. A one-celled organism that does not have a membrane-bound nucleus.

Prokaryotes are single-celled organisms.

They do not have a membrane around their nucleus like eukaryotes do. The region where the cell's DNA is located is called the nucleoid. The DNA is a single, circular chromosome.

Prokaryotes do have a cell wall, however they are single celled organisms.

Hope this helps!
