MEDICAL PHYSIOLOGY

Detailed explanation-1: -All prokaryotic cells have a stiff cell wall, located underneath the capsule (if there is one). This structure maintains the cell’s shape, protects the cell interior, and prevents the cell from bursting when it takes up water.

Detailed explanation-2: -Extracellular matrix material is not associated with these cells. Prokaryotic cells have a fairly rigid cell wall but this is not made of cellulose as it is in plants. This type of cell is found in all higher animal and plant cells and contains membrane bound organelles and a well defined nucleus.

Detailed explanation-3: -All prokaryotes have plasma membranes, cytoplasm, ribosomes, a cell wall, DNA, and lack membrane-bound organelles. Many also have polysaccharide capsules. Prokaryotic cells range in diameter from 0.1–5.0 µm.

Detailed explanation-4: -Final answer: The structure which is not found in a prokaryotic cell is the nuclear membrane.
