Cell division, also called mitosis, occurs in multicellular organisms to create tissues, organs and organ systems. It is a method of asexual reproduction in unicellular organisms, and it occurs because it’s essential for increasing the population of the organisms.
Every organism is composed of cells and originates from pre-existing cells. Mitosis is the process of generating new cells, and it involves distributing identical DNA to separate daughter cells. Karyokinesis is the phase of mitosis in which the nucleus divides, and the cytoplasm divides during cytokinesis.
Mitosis takes one to two hours. During interphase, which occurs between two cell divisions, the cell produces a copy of its chromosome material. Interphase is called the cell cycle when cell division precedes it.
Mitosis serves as a vital part of a multicellular organism’s growth. New cells are created for the purpose of renewing tissues and replacing weary cells. In humans and other animals, mitosis occurs in specialized tissues found in organs. Mitotic division and cell growth continuously occur as the embryo develops. The fertilized egg divides intp the skin, long bones and lymph glands.
Plants have special cells that separate in an area behind the edge of the radicle or plumule, allowing new cells to form. Once the cells develop, the roots and stem grow bigger, and the buds can turn into flowers, leaves or branch stems.
