Question

Binary fission is the division of the parent body into how many parts?
A. Three
B. Four
C. Two
D. Nine

Answer 1

Hint: Binary fission is the mode of asexual reproduction in which a single parent is involved in the production of the new generation. It starts with the replication of the DNA, followed by the growth of the cell, then segregation of the DNA, and finally splitting of the cells. The organism that reproduces by binary fission includes Amoeba.

Complete answer:
If we cut an organism into two halves from the middle in a single plane then it will give rise to two parts, both of them will grow independently to form a new organism and will be the same as the mother cell,
Hence option C is the correct option.
In the process of binary fission the parent cell is cut into equal halves from the middle after the replication of DNA.
Hence option A is incorrect.

As the organism is cut through the middle, it cannot form four parts.
Hence option B is incorrect.

Cutting of a cell into nine parts requires cutting from more than one plane but in binary fission, the cut occurs from a single plane (vertically) from the middle,
hence option D is incorrect.

Note:
The main advantages of binary fission include – a. The occurrence of the process of binary fission is very rapid and also does not require the involvement of a large amount of energy. No genetic variation is seen in the daughter and the mother cell and the daughter cell can be termed as a clone of the mother cell. Stable environments with less change are favorable for this mode of reproduction.
