Detailed explanation-1: -In all complex multicellular organisms (eukaryotes), cell duplication occurs by a process called “mitosis” or cell division.
Detailed explanation-2: -Mitosis is a phase of the cell cycle in which a cell’s nucleus is divided into two nuclei, each with an equal quantity of genetic material. It is an asexual reproductive process that occurs in unicellular organisms. Thus, mitosis is a type of cell division that occurs during the asexual reproduction process.
Detailed explanation-3: -Multicellular organisms also reproduce asexually and sexually; asexual, or vegetative, reproduction can take a great variety of forms. Many multicellular lower plants give off asexual spores, either aerial or motile and aquatic (zoospores), which may be uninucleate or multinucleate.
