What is the difference between meiosis 1 and meiosis 2? a. What is the process of sexual reproduction? b. Why do we say that meiosis is essential for sexual reproduction? c. When do cells regain the normal chromosome number of body (somatic) cells? d. How does the alternation of meiosis...
What are the individual DNA molecules in a cell called, which become visible as tightly coiled bundles during mitosis and meiosis? What is the term that refers to the division of the cytoplasm following mitosis to form two daughter cells?
Meiosis is a type of cell division that reduces the number of chromosomes in the parent cell by half and produces four gamete cells. This process is required to produce egg and sperm cells for sexual reproduction. ... Meiosis begins with a parent cell that is diploid, meaning it has two ...
Both mitosis and meiosis are types of cell division that involve the segregation of chromosomes into daughter cells. However, there are many important differences between these two cellular processes.Mitosis is considered an “equational” form of cell division — it occurs in cells that do not ...
The Sertoli cells produce thehormone inhibin, which is released into the blood when the sperm count is too high. What is the function of spermatogenic cells? The spermatogenic cellsdivide by mitosis, then meiosis to form gametes, which mature into sperm by the process of spermiogenesis. Unusually...
of the plant. moreover, this type of meristem is completely undifferentiated and responsible for primary growth. what is the function of the apical meristem? unlike undifferentiated plant cells, differentiated plant cells generally cannot divide or even produce different types of cells. however, ...
First, the division part of the cell cycle—mitosis—is so important becausethe parent cell passes its genetic information to its offspring cells(sometimes called “daughter” cells) during this type of cell division. If cell division doesn’t occur, new cells can’t be created. And it’s ...
The cells of an animal or higher plant have two sets of chromosomes: they are diploid. When gametes (sex cells) are produced, they have onlyone set of chromosomes: they are haploid. They have undergone a process of cell division calledmeiosis. During meiosis, crossing over occurs. This make...
gondii line incapable of completing its life cycle with reduced virulence. At the same time, the strain’s antigenicity is retained to elicit an immune response in the host, allowing it to produce memory cells and prevent reinfection. Currently, only one live attenuated vaccine, Toxovax®, is...
