Multicellular eukaryotes are made of two fundamental cell types: germ and somatic. Germ cells produce gametes and are the only cells that can undergo meiosis as well as mitosis. These cells are sometimes said to be immortal because they are the link between generations. Somatic cells are all the other cells that form the building blocks of the body and they only divide by mitosis. The lineage of germ cells is called the germline. Germ cell specification begins during cleavage in man… WebBones make up the internal framework and provide structural support for the human body.
