NEET BIOLOGY

Detailed explanation-1: -Eukaryotes use two major types of cell division: mitosis and meiosis. Mitosis is used to produce new identical somatic (body) cells for growth and healing, while meiosis is used to produce sex cells (eggs and sperm). Meiosis will be discussed in a later chapter.

Detailed explanation-2: -Mitosis Examples Apart from stem cells, other mitotically active cells are progenitor cells and blast cells (precursors). Both of them divide but not as indefinitely as the stem cells. Cancer cells are another example.

Detailed explanation-3: -Mitosis creates identical copies of cells. For example, it creates new skin cells to replace dead skin cells.

Detailed explanation-4: -There are two types of cell division: mitosis and meiosis. Most of the time when people refer to “cell division, ” they mean mitosis, the process of making new body cells. Meiosis is the type of cell division that creates egg and sperm cells. Mitosis is a fundamental process for life.

Detailed explanation-5: -During mitosis, a eukaryotic cell undergoes a carefully coordinated nuclear division that results in the formation of two genetically identical daughter cells. Mitosis itself consists of five active steps, or phases: prophase, prometaphase, metaphase, anaphase, and telophase.
