Answer:
By meiosis
Explanation:
Well, it can happen in different ways. One way is called binary fission. This is where a single-celled organism copies its DNA, then divides into two cells. Another way is called fragmentation. This is where a piece breaks off the organism, forming a new individual.
In this process, a single celled organism will slowly grow another cell on the outside of its body called the daughter cell. The nucleus of the main cell splits into two and becomes part of the daughter cell. When this new daughter cell is large enough to survive on its own, it breaks off from the bigger cell.
