Mitosis, a key part of the cell cycle, involves a series of stages (prophase, metaphase, anaphase, and telophase) that facilitate cell division and genetic information transmission. Centrosomes and microtubules play pivotal roles in orchestrating this complex process, ensuring the successful replication of cells. Created by Sal Khan.
Its goal is to make daughter cells with exactly half as many chromosomes as the starting cell. To put that another way, meiosis in humans is a division process that takes us from a diploid cell—one with two sets of chromosomes—to haploid cells—ones with a single set of chromosomes. In humans, the haploid cells made in meiosis are sperm ...

Jan 1, 1987 · Publisher Summary. The simplest description of cell reproduction is that cells grow and then divide. On an average, a cell doubles its size from one division to the next. Although growth is ultimately essential for cell reproduction, the connection between growth and cell division is more circuitous and complicated than a simple microscopic ...
Figure 10.2.2 10.2. 2: There are 23 pairs of homologous chromosomes in a female human somatic cell. The condensed chromosomes are viewed within the nucleus (top), removed from a cell in mitosis and spread out on a slide (right), and artificially arranged according to length (left); an arrangement like this is called a karyotype.
Once a human individual is fully grown, cell reproduction is still necessary to repair or regenerate tissues. For example, new blood and skin cells are constantly being produced. All multicellular organisms use cell division for growth, and in most cases, the maintenance and repair of cells and tissues.
