NEET BIOLOGY

Detailed explanation-1: -Mitosis itself consists of five active steps, or phases: prophase, prometaphase, metaphase, anaphase, and telophase. Before a cell can enter the active phases of mitosis, however, it must go through a period known as interphase, during which it grows and produces the various proteins necessary for division.

Detailed explanation-2: -Mitosis happens in all eukaryotic cells (plants, animals, and fungi). It is the process of cell renewal and growth in a plant, animal or fungus.

Detailed explanation-3: -The reproductive cells or the sexual gametes-egg and sperm do not undergo the phenomenon of mitosis as they perform meiosis. The prokaryotic cells also do not exhibit mitosis and do not contain the structure needed for it. Therefore, all cells do not exhibit mitosis.

Detailed explanation-4: -Mitosis consists of four basic phases: prophase, metaphase, anaphase, and telophase. Some textbooks list five, breaking prophase into an early phase (called prophase) and a late phase (called prometaphase).

Detailed explanation-5: -Somatic cells, adult stem cells, and the cells in the embryo are the three types of cells in the body that undergo mitosis. Mitosis is a process of nuclear division in eukaryotic cells that occurs when a parent cell divides to produce two identical daughter cells.
