Biology Assessed practical Coursework 1 Mitosis in garlic root cells Mitosis is the division of one cell to form 2 daughter cells, mainly found useful for repairing tissue, replacing cells and is also used in asexual reproduction. Mitosis can also be named, nuclear division. Nuclear division is divided into four stages, Prophase, metaphase, anaphase, telophase. The first stage, Prophase, is where nuclear division begins. In early prophase, the centriole replicates itself and the chromosomes begin to coil up; they become shorter, thicker, stain more intensely and become much more visible. During late prophase, the centrioles move to opposite poles of the nucleus and the nuclear envelope 'disappears' (it breaks up into small vesicles not visible by a light microscope). The nucleolus disappears to form parts of chromosomes. The second part of nuclear division is metaphase. In this stage the chromosomes line up along the equator of the spindle (in the centre of the 2...
