Detailed explanation-1: -Mitosis plays an important part in the life cycle of most living things, though to varying extents. In unicellular organisms such as bacteria, mitosis is a type of asexual reproduction, making identical copies of a single cell. In multicellular organisms, mitosis produces more cells for growth and repair.
Detailed explanation-2: -In unicellular organisms, cell division is important for reproduction only. They produce their daughter cells by the mitosis type of cell division. In multicellular organisms, cell division is important for producing new body cells and reproduction.
Detailed explanation-3: -Mitosis is the process in cell division by which the nucleus of the cell divides (in a multiple phase), giving rise to two identical daughter cells. 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-4: -In the case of multicellular organisms, mitosis helps in growth and repair by producing more number of identical cells. For example plants, animals depend on cell division for their growth by addition of new cells.
Detailed explanation-5: -Both unicellular and multicellular organisms undergo mitosis. What are the differences, if any, observed in the process between the two?
