Bipalium kewense is a species of flatworm that can reproduce sexually; however, instead it usually breaks into two pieces, each of which becomes a fully functioning adult. what is the main method of reproduction for these flatworms? binary fission fragmentation sporulation fertilization

The correct answer is B. Fragmentation

Explanation:

The term "fragmentation" refers to a type of reproduction that occurs mainly in multicellular organisms and occurs as one organism divides or fragments and each of the fragments is able to mature and become identical to the original organism. This type of asexual reproduction occurs in certain bacterias, plants, flatworm, worms, and sea stars. This type of reproduction differs from others such as binary fission because binary fission occurs only in single-celled organisms that divide into two identical cells. Considering the previous ideas, it can be concluded in the case of the flatworm described in the question the type of reproduction is fragmentation, considering the flatworm divides into two fragments and then each fragment becomes an adult.
