WebProkaryotes do not have membrane-bound organelles, such as mitochondria or an endoplasmic reticulum. Flagella are hair-like structures that allow the cell to move, and are present in both prokaryotes and eukaryotes. Although prokaryotes don't have multiple chromosomes like eukaryotes, they do still have DNA in the form of a cyclic chromosome. WebEndothelial cells are the cells that form the inner lining of the blood vessel. Cell surface proteins on the white blood cell interact and bind to the cell surface proteins on the lining of the blood vessel to slow down and stop the white blood cell.
