What is mitosis not used for?
It happens in the cells of the body known as the somatic cells and produces cells related to growth and repair. Mitosis is essential for asexual reproduction, regeneration, and growth. It does not make sex cells or gametes.What cells do not use mitosis?
Skin cells, red blood cells or gut lining cells cannot undergo mitosis.Which organisms use mitosis and which do not?
Mitosis occurs only in eukaryotic cells. Animal cells undergo “open” mitosis, where the nuclear envelope breaks down before the chromosomes separate, whereas fungi undergo “closed” mitosis, where chromosomes divide within an intact cell nucleus.- The statement that is NOT true is: "The cells resulting from meiosis are diploid and the cells resulting from mitosis are haploid." This statement is incorrect as the cells resulting from meiosis are actually haploid, meaning they have half the number of chromosomes as the parent cell.
