Gametes are produced by mitosis (not meiosis) and after fertilization a diploid zygote is created. … It can only divide by meiosis to produce haploid cells once more, which then produce the main adult body. In plants and some algae, there is a multicellular diploid and a multicellular haploid period of the life cycle.
Do gametes go through the cell cycle?
Since cell division occurs twice during meiosis, one starting cell can produce four gametes (eggs or sperm). In each round of division, cells go through four stages: prophase, metaphase, anaphase, and telophase.
Do human gametes undergo mitosis?
Whereas somatic cells undergo mitosis to proliferate, the germ cells undergo meiosis to produce haploid gametes (the sperm and the egg).
What cell division occurs in gametes?
Meiosis, from the Greek word meioun, meaning “to make small,” refers to the specialized process by which germ cells divide to produce gametes. Because the chromosome number of a species remains the same from one generation to the next, the chromosome number of germ cells must be reduced by half during meiosis.
Do gametes divide during mitosis?
Mitosis is common to all eukaryotes; during this process, a parent cell splits into two genetically identical daughter cells, each of which contains the same number of chromosomes as the parent cell. … During meiosis, the cells needed for sexual reproduction divide to produce new cells called gametes.
What kind of cells undergo meiosis?
What types of cells undergo meiosis? Only those that produce gametes, e.g. eggs in females and sperm in males.
What type of cell undergoes meiosis gamete or somatic?
1) Somatic cells undergo mitosis whereas gamete cells undergo meiosis. Mitosis takes place throughout the lifetime of an organism.
