Labeled diagram of mitosis and meiosis. This is the currently selected item. Read on to explore what is mitosis and the different stages of. Differing from the metaphase stage of mitosis the centromeres of chromosome pairs in metaphase stage of meiosis i become attached with the spindle fibres near the equatorial region. Mitosis is a means of asexual reproduction whereas meiosis is necessary for sexual reproduction.
The centromeres remain clearly apart from each other and face the opposite poles while the arms of the chromosome pairs lie towards the equator. Mitosis is a process of cell division which results in the production of two daughter cells from a single parent cell. Cell cycle regulation cancer and stem cells. Chromosomal crossover in meiosis i.
Labeled diagram mitosis is a process of cell division which results in the production of two daughter cells from a single parent cell. Mitosis definition mitosis is that step in the cell cycle where the newly formed dna is separated and two new cells are formed with the same number and kind of chromosomes as the parent nucleus mitosis is a process of asexual reproduction observed in unicellular organisms. Mitosis is the process of cell division that forms two genetically identical nuclei from on parent cell nucleus. Chromosomes condense nuclear membrane dissolves mitosis.
Meiosis is the division of a germ cell into four sex cells e g. Paramecium growth increasing cell number repair and maintenance replace damaged cells with identical replacements. Meiosis i segregates homologous chromosomes which are joined as tetrads 2n 4c producing two haploid cells n chromosomes 23 in humans which each contain chromatid pairs 1n 2c because the ploidy is reduced from diploid to haploid meiosis i is referred to as a reductional division meiosis ii is an equational division analogous to mitosis in which the sister chromatids are. Illustration of the process by which somatic cells multiply and divide.
The daughter cells are identical to one another and to the original parent cell. The daughter cells are. Phases of meiosis i. Egg or sperm each with half the number of chromosomes of the parent cell.
We are pleased to provide you with the picture named mitosis and meiosis diagram we hope this picture mitosis and meiosis diagram can help you study and research. Labeled diagram mitosis is a process of cell division which results in the production of two daughter cells from a single parent cell. Comparing mitosis and meiosis. The daughter cells are identical to one another and to the original parent cell.
Phases of meiosis ii.
