It states that all cells within an individual share identical DNA stored in chromosomes, with species-specific chromosome numbers. When cells divide, chromosomes and DNA must be accurately duplicated and distributed, forming two new cells with equal genetic material. The cytoplasm and organelles are also partitioned, with mitosis handling nuclear DNA distribution and cytokinesis completing cell separation.

The cell theory states \"All cells come from preexisting cells by a process of cell reproduction , or cell division \" .  \nMitotic cell division is the process by which all cells of a multicellular organism are formed. Cell division is also responsible for repair and replacement of cells and tissues during one's lifetime, and for asexual reproduction, a means of making more individuals common in protists, fungi, many plants and some animals.  \nWe know that all cells of an individual have exactly the same DNA, and their DNA is found in structures called chromosomes. Each species has a fixed chromosome number, a number that does not change from generation to generation. The DNA must also stay the same from cell to cell within an organism, so that when cells divide, new cells formed will have exactly the same DNA as the original cell.  \nTo ensure that chromosomes and DNA remain the same in new cells, the following must take place when cells divide:  \n• We must form two new cells from the original cell.  \n• Since each cell must have all of the genetic material for the organism, we must have a mechanism that exactly duplicates the DNA from the original cell and distributes the copied DNA equally to the new cells. The distribution of DNA into new nuclei during cell division is called mitosis. (Duplication of DNA is apart of the discussion of structure and function of DNA.)  \n• We must also separate the cytoplasm, and critical organelles, such as mitochondria and chloroplasts, of the original cell into the new cells formed so that the new cells can survive, grow and function. The separation of cytoplasm into new cells is called cytokinesis.  \nMitotic cell division is the process by which all cells of a multicellular organism are formed. Cell division is also responsible for repair and replacement of cells and tissues during one's lifetime, and for asexual reproduction, a means of making more individuals common in protists, fungi, many plants and some animals.  \nIn our discussion of cell reproduction, we shall focus on the processes of cell reproduction (mitosis and cytokinesis) in eukaryotic organisms. The process of cell division in prokaryotic organisms, binary fission , has similarities, but the single molecule of DNA and absence of a nucleus in the prokaryotic cell account fora number of differences in the \"mechanics\" of the process.  \nIn addition, in sexually reproducing organisms, a variation of cell reproduction, called meiosis , occurs at one stage in the organism's life cycle (to form gametes in animals, or to start the gamete producing stage in plants) . We will discuss the process of meiosis later.  \nCell Reproduction: Mitosis - 2  \nBefore discussing how cells divide , it 's probably useful to discuss the structure of chromosomes and chromosome terms (of which there area sufficiency) .  \nStructure of Chromosomes  \nChromosomes are composed of DNA and protein, a mixture called chromatin. During the normal metabolic activities of the cell the collective DNA, or chromatin, appears dense and grainy.  \nDNA is a thread-like double chain of nucleotides. The DNA coils around the histone proteins to form nucleosomes. Chromosomes continue to tightly coil and fold back on themselves prior to cell division. Chromosomes are visible only when  \ntightly coiled.  \nEach species has a characteristic number of chromosomes. Humans have 46 chromosomes; potatoes and chimpanzees have 48 chromosomes. The pea plant, important in Mendelian genetics has 14, the even more famous fruit fly has 8. Some ferns have chromosome numbers exceeding 1000. Chromosomes are selfduplicating and must do so prior to each cell division. There is an essential vocabulary associated with chromosome appearance before and after duplication.  \nCell Reproduction: Mitosis - 3  \nChromosome Terms before and after Duplication  \n• An unduplicated chromosome is one chromosome.
