- Dall the three
Correct answer
B. amitosis
Step-by-step solution
There are three types of cell divisions namely amitosis, mitosis, and meiosis. In amitosis, the chromosomes do not become visible. It is found in primitive life forms such as amoeba, bacteria, etc. The nucleus elongates in a dumb-bell shape and is followed by the invagination of the plasmalemma. The constriction in the nucleus, as well as plasmalemma, deepens and divide one amoeba into two daughter amoebae.
