<Li> Eukaryotes: Eukaryotic cells are also surrounded by the plasma membrane, but on the other hand, they have distinct nuclei bound by a nuclear membrane or envelope . Eukaryotic cells also contain membrane - bound organelles, such as (mitochondria, chloroplasts, lysosomes, rough and smooth endoplasmic reticulum, vacuoles). In addition, they possess organized chromosomes which store genetic material . </Li> <P> Animals have evolved a greater diversity of cell types in a multicellular body (100--150 different cell types), compared with 10--20 in plants, fungi, and protoctista . </P>
