    Fundamental of Cell Biology A cell is the basic unit of life‚ and all organisms are made up of one or many cells. One of the things that all cells have in common is a plasma membrane‚ it is also called as cell membrane as it is works as a barrier between the inner and outer surface of a cell. In animal cells‚ the plasma membrane is present in the outer most layer of the cell and in plant cell it is present just beneath the cell wall. It separates the contents of the cell from its outside environment

    Mitosis Mitosis is the process where a cell divides‚ to create two diploid cells identical to the first other than for a small bit of protein that lets the cell know how many times it has divided. 1. The cell duplicates its chromosomes so that it now has double as many‚ but they remain attached. 2/3. The cell begins to split until it has the chromosomes have separated completely‚ to form two separate set of chromosomes. The cell begins to divide. 4. The cell divides completely to form two diploids

    Meiosis BIOL 1111 Introduction Meiosis is the second important kind of nuclear division. It resembles mitosis in many ways but the consequences of meiotic divisions are very different from those of mitotic divisions. While mitotic division may occur in almost any living cell of an organism‚ meiosis occurs only in special cells. In animals‚ meiosis is restricted to cells that form gametes (eggs and sperm). Each species has a characteristic number of chromosomes per somatic cell. Fruit flies

    Why do cells divide? There are many reasons for this. Cells absorb and release nutrients threw their membrane. The larger the cell‚ the harder it is to get rid of all the waste that is produced. So‚ if there are many small cells (more surface area) rather than one large cell‚ the waste can be disposed of more readily. The other 3 reasons are critical to the survival of all organisms: Growth‚ repair and reproduction. • Growth: This is a result of mitosis. The more cells in an organism‚ the larger
