Germ Cells vs. Somatic Cells
Germ cells refer to a living cell that gives rise to the gametes of an organism whereas somatic cells are any biological cell develop in the body of an organism; that is, undifferentiated stem cell or gametocyte in a multicellular organism. Somatic cells are also known as vegetal cells. In many animals, the germ cells initiate in the primeval line and migrate to the developing gonads via the gut of an embryo. In mammals, somatic cells make up all the internal organs, bones, skin, connective tissue, and blood. In mammalian, germ cells give rise to ova and spermatozoa which fuse and produce a cell called a zygote during fertilization, which differentiates into the cells of an embryo. In germ cells when a mutation occurs it transfer to the next generation by sexual generation. About 220 types of somatic cells in the human body are present, and they never transmit to their progenies since they are not involved in sexual reproduction. Germ cells are the only cells that can undergo meiosis as well as mitosis during sexual reproduction and produce haploid gametes. Somatic cells only divide by mitosis during asexual reproduction that forms the building blocks of all the other cells of the body of animals.
What are Germ Cells?
Germ cells are a cell that gives rise to gametes and refers to one set of the chromosome into the daughter cells and can transfer genetic information to next generations as they are the link between generations as sometimes said to be immortal. Germ cells are the only cells in which both meioses, as well as mitosis, occur. The heredity of germ cells is called germ line. Germ cell arrangement begins in the epiblast during cleavage in many animals and gastrulation in mammals and birds. Sometimes mutation occurs for example Germ cell tumor is rare cancer that can affect people at all ages mainly children and it counts for 4% of all cancers cases. Germ cells are cells that can reproduce and produce gametes through sexual reproduction in living organisms germ cells in a living organism such as animals transfer and travel to the gonads as came from the embryo’s gut. Germ cells can explain how we can evolve and vital in the perception of reproduction in organisms such as in humans.
Examples
Sperms cells of male and egg cells of the female.
What are Somatic Cells?
The regular cell of the body other than sperm and gamete is called somatic cells. Somatic cells are only divided by mitosis and contain all the cells other than germ cells and form the building blocks of the body. Typically, somatic cells are produced by mitosis in asexual reproduction in humans and are diploid as two sets of homologous chromosomes are present in the nucleus of a human. Some species may consist of polyploid or diploid somatic cells. The polyploid somatic cells are generally present in plants. In humans, continuous mitotic cell divisions occur into the multicellular organism, and the fusion of a sperm cell forms the diploid zygote. The human body contains more than three trillion somatic cells. These somatic cells are distributing into four major types of tissues in the body known as connective tissue, epithelial tissue, nerve tissue, and muscles tissues. Tissues form organs and organs form organ systems. Mutations occur in somatic cells since they play no role in sexual reproduction as they cannot contribute to evolution. Cloning is used to produce the same genetic clones of animals. In the somatic cell, the nucleus is removed from the cell and injected into an ovum of another individual of the same species. The genetic material of the animal has removed before the injection of the somatic cell in the nucleus. Somatic cells can tell us how we can have bones, organ, and tissues since these types of cells are responsible for the structures of the body.
Examples
Present in bones, skin muscle and nerve cells.
