Listen to a recorded reading of this page:.Take a ten question quiz about this page.Next, the cell wall 'pinches' off in the middle forming two separate cells. Then the duplicate strands of DNA move to opposite sides of the cell. First the DNA replicates and the cell grows to twice its normal size. Simple organisms such as bacteria undergo a type of cell division called binary fission. The splitting of the cells is called cytokinesis or cell cleavage. The two new cells, or daughter cells, are formed. The cell walls then pinch off and split down the middle. Telophase - During telophase the cell forms two nuclear membranes around each set of chromosomes and the chromosomes uncoil.Anaphase - During anaphase the chromosomes separate and move to opposite sides of the cell.Metaphase - During metaphase the chromosomes line up along the middle of the cell.Prophase - During this phase the chromatin condenses into chromosomes and the nuclear membrane and nucleolus break down. In cells without a nucleus (prokaryotic), the cell cycle occurs via a process termed binary fission.When a cell gets the signal that it is to duplicate, it will enter the first state of mitosis called the 'prophase'. membrane bound organelles Reproduces by binary fission Undergoes Mitosis/Meiosis to. In this method, a single-celled organism divides into two daughter cells, and each daughter cell. binary fission: the process whereby a cell divides asexually to produce two daughter cells. It is a simple & common method of asexual reproduction. karyokinesis: (mitosis) the first portion of mitotic phase where division of the cell nucleus takes place. The genetic material is duplicated during the interphase stage of the cell. Cell Biology Biology: Chapter 7 - Cell Structure and Function. mitotic spindle: the apparatus that orchestrates the movement of DNA during mitosis. The 'normal' state of a cell is called the 'interphase'.

The full process, or cycle, of mitosis is described in more detail below.Įxamples of cells that are produced through mitosis include cells in the human body for the skin, blood, and muscles.Ĭells go through different phases called the cell cycle. The original cell is called the mother cell and the two new cells are called daughter cells. The two new cells have the same DNA, functions, and genetic code. Mitosis is used when a cell needs to be replicated into exact copies of itself. More complex organisms gain new cells by either mitosis or meiosis. Binary fission is used by simple organisms like bacteria. There are three main types of cell division: binary fission, mitosis, and meiosis. Around two trillion cell divisions occur in the average human body every day! The process by which new cells are made is called cell division. They make new cells in order to grow and also to replace old dead cells. Living organisms are constantly making new cells.
