Biology Chapter 4 Diagram Quizlet 1.centrally located genetic material. 2.cytoplasm. 3.plasma membrane. what are some characteristics of prokaryotic cells? •simplest organisms. •lack a membrane bound nucleus. •cell wall outside of plasma membrane. •contain ribosomes. •no membrane bound organelles. Unlike prokaryotic cells, eukaryotic cells have: 1) a membrane bound nucleus; 2) numerous membrane bound organelles such as the endoplasmic reticulum, golgi apparatus, chloroplasts, mitochondria, and others; and 3) several, rod shaped chromosomes. because a membrane surrounds eukaryotic cell’s nucleus, it has a “true nucleus.”. Components of prokaryotic cells. all cells share four common components: 1) a plasma membrane, an outer covering that separates the cell’s interior from its surrounding environment; 2) cytoplasm, consisting of a jelly like cytosol within the cell in which there are other cellular components; 3) dna, the cell's genetic material; and 4. 4.2 prokaryotic cells. prokaryotes are single celled organisms of the domains bacteria and archaea. all prokaryotes have plasma membranes, cytoplasm, ribosomes, and dna that is not membrane bound. most have peptidoglycan cell walls and many have polysaccharide capsules. prokaryotic cells range in diameter from 0.1 to 5.0 μm.
