WitrynaMitosis results in two nuclei that are identical to the original nucleus. Meiosis, on the other hand, results in four nuclei, each having half the number of chromosomes of the original cell. In animals, meiosis only occurs in the cells that give rise to the sex cells (gametes), i.e., the egg and the sperm. Also read: Cell Cycle WitrynaCells divide by mitosis for growth and repair. They divide by meiosis to produce gametes for sexual reproduction. Stem cells differentiate into specialised cells during …

WitrynaMeiosis occurs in the male flower parts to produce pollen (represented by the green circle) and the female floral organs produce egg cells (represented by the white circle). Spores grow by mitosis producing more haploid cells, this is the gametophytic generation. We get a brief glimpse of the gametophytic generation when pollen is … WitrynaMeiosis produces our sex cells or gametes (eggs in females and sperm in males). Meiosis can be divided into nine stages. These are divided between the first time the … WitrynaTo observe an individual’s karyotype, a person’s cells (like white blood cells) are first collected from a blood sample or other tissue. In the laboratory, the isolated cells are stimulated to begin actively dividing. A chemical is then applied to the cells to arrest mitosis during metaphase. The cells are then fixed to a slide. お礼状 英語 贈り物 ビジネス
