Experiment Mitosis - Essay warningCell division is a primeval butt in both plants and animals growth and phylogeny as well as recreation. This paper investigates the mitosis process in both plants and animals cellular phones to identify distinct forms of mitosis and the structure of cells at distributively stage. The experiment identifies similarity in mitotic stages for cells in both plants and animals. The mitotic process leads to division of one evoke cell to form two identical daughter cells that can further undergo subsequent mitotic divisions. opening Cells are the fundamental elements of living things, both plants and animals. Consequently, realized mechanisms originate from cells and manifest in organs and the total organism. Mitosis and meiosis are some of the fundamental processes that take bulge out at the cell level. They refer to cell divisions that lead to generation of new cells to replace dead or worn out cells, generation of cells for development of organ s, and cell division towards growth. Mitosis leads to generation of identical daughter cells for growth or replacement of cells in organs. It takes place in a number of stages, interphase, prophase, metaphase, anaphase, telophase, and cytokinesis (Goldberg and Goldberg, p. 77- 80). The interphase is a preliminary stage in cell division that precedes the mitotic stages. It is fundamental as it forms the largest percentage of a cells life. The major activity at this stage is retort of cell proteins within cells and developments to visibility of cell nucleoli. Mitosis however has four stages that result into cell division. The first stage is the prophase, followed by metaphase, anaphase, and telophase respectively (Goldberg and Goldberg, p. 79). At the prophase, strands of chromosomes begin to condense and can be seen with the aid of a power microscope. Visibility of the nucleoli however disappears while fibers develop in the cells cytoplasm. The developed fibers emanates from a duad of centrosomes that stretch to opposite poles of the cytoplasm. Disintegration of the nuclear membrane begins at this stage and marks the end of the prophase and the process moves to the metaphase (Goldberg and Goldberg, p. 79). At the metaphase stage, the chromosomes are arranged along a plate that is perpendicular to the centrioles plane and the spindle fibers unite the centrosomes and the chromosomes (Goldberg and Goldberg, p. 79). A new phase, the anaphase is consequently marked by disintegration of chromosomes into centromeres that are then attracted to the centrosomes along the fibers (Goldberg and Goldberg, p. 79). The cell then enters a new phase, the telophase, where the pulled chromosomes converge at the opposite sides of the cell, along the fibers and the nuclear membrane begins to reappear. all(prenominal) set of chromosomes assumes the normal thread like structure and the nuclear membrane develop around each group of chromosomes to form two nucleuses within the cytop lasm (Toole and Toole, p. 139). The cytokinesis process, where the cytoplasm divides to form two different cells then follows this (Goldberg and Goldberg, p. 79- 80). The structure of the cells in plants and in animals may however be different. This is because of a number of factors such as the lack of significance of the spindle fibers in the plant cells. The nucleus, rather than spindle fibers in plant cells, moves to do the new position of chromosomes in the mitosis process (Cassimeris, Plopper and Lingappa, p. 952). This paper seeks to explore mitosis in plants and animals cells. It aims at describing chromosomal events in mitosis, differentiating between plants and animal cytokinesis, and explaining why mitotic divisions are necessary in living systems.
