3.19 understand that division of a diploid cell by mitosis produces two cells which contain identical sets of chromosomes

3.19 •diploid cell: cells with a full 23 pair set of chromosomes 

                  •asexual reproduction involves mitosis, where the ordinary cell divides into two 

                  •asexual reproduction is from one parent, so there is no variation 

                   

        •process of mitosis 

                  •1. the cell duplicates its DNA, forming ‘X’ shaped chromosomes - each arm is the exact duplicate of the other

                  •2. the chromosomes line up at the centre of the cell and cell fibres pull them apart, leaving the two arms of the ‘X’ at opposite ends

                  •3. membranes form around each of the sets of chromosomes , becoming the nuclei of the two new cells

                  •4. the cytoplasm divides, leaving you with two identical cells
