Answer
Mitotic
Explanation
Mitotic cell division is a process of cell division that produces two daughter cells genetically identical to the parent cell. It maintains the same diploid number of chromosomes in each new cell, ensuring chromosome number remains constant across generations of cells. This is essential for growth, repair, and asexual reproduction in multicellular organisms.
