Explanation:
Detailed explanation-1: -In all complex multicellular organisms (eukaryotes), cell duplication occurs by a process called “mitosis” or cell division.
Detailed explanation-2: -In meiosis the germ cell divides into four sex cells, each cell consisting of half of the parent cell’s chromosomes. Mitosis is necessary for cell growth, repair, and regeneration. Dead cells are replaced by mitosis since the number of chromosomes is not changed in a cell after division in mitosis.
Detailed explanation-3: -In multicellular organisms individual cells grow and then divide via a process called mitosis, thereby allowing the organism to grow.
