Biology Inheritance – Mitotic Squash of Garlic Root Tip Mitosis is the process of cell division; it is the process by which a eukaryotic cell separates the chromosomes in its cell nucleus into two identical sets in two nuclei. It is generally followed immediately by cytokinesis‚ which divides the nuclei‚ cytoplasm‚ organelles and cell membrane into two cells containing roughly equal shares of these cellular components. Mitosis and cytokinesis together define the mitotic phase of the cell cycle—the

Practical 1: Observation of mitosis in garlic root tips Introduction The practical will involve the preparation‚ observation‚ and classification‚ of the various stages of mitosis by observing garlic root tips using a microscope. The study comes under the heading of cytogenetics which is the visual characterisation of genetic material and the study of how that material reacts during the life of the cell. Strictly speaking‚ mitosis is the division of the nucleus into two daughter nuclei that are
