Meiosis Cell Division

Meiosis Cell Division

Hi Viewer: Today we will discuss another very important cell function, which is known as Meiosis Cell Division.  Meiosis cell division do occur in plant cell and as well as in animal cell.  Living organisms produce gametes by this process.  It is very complicated too.  So let us check out what happens in the process, which is described below. Meiosis  Definition: Meiosis is the germ mother cell division in which the chromosome number of the mother cell is reduced to half in each daughter cell (reductional division). Site of occurrence:  In plant meiosis occurs in the microspore mother cell and megaspore mother cell and in animal it occurs in the germ mother cell of the testis and ovary.   PROPHASE 1 Leptotene (lepto-thin/tene-band): Chromosomes start to dehydrate It appears as distinct longitudinal threads 4.  Each chromosome has a beaded appearance 5.  The appearance is for the chromomeres 6.  In some insects the chromosomal ends are arranged in a particular direction. This is called a bouquet stage. N.B.   Draw two centrioles...
