The cellular materials often appear to move, or stream, within the cell. If cell walls are present in the cell, they are usually composed of cellulose or another carbohydrate, chitin. Cell division of eukaryotic cells includes mitosis and cytogenesis. There are many differences in prokaryotic cells and Eukaryotic cells. The biggest difference between the two types of cells is their membrane- enclosed structures.
Eukaryotes have many membrane- bound organelles.
Their genetic material, DNA, is closely associated with proteins and, when the cell divides, it appears as multiple structures called chromosomes. Prokaryotes just have a simple, circular DNA, with fewer proteins attached. This can produce movement within the cell, give the cell a definite shape, and organize the transport of vital molecules. The flagella of prokaryotes are much simpler, composed of a single protein fibril. Several other chemical differences exist between the two groups, with prokaryotes showing a much greater diversity of metabolic processes.
