Question

Assertion (A): Binary fission in {Paramecium} is called perkinetal fission.
Reason (R): Plane of fission in {Paramecium} is at right angles to longitudinal axis of the body.

• (A) and (R) are true. (R) is correct explanation for (A)
• (A) and (R) are true. But (R) is not the correct explanation for (A)
• (A) is true, but (R) is false
• (A) is false, but (R) is true

Hint:

Different types of fission depend on the plane of division relative to the cell’s axis.

Answer 1

The Correct Option is B

In perkinetal fission of {Paramecium}, the axis of fission is transverse, hence both A and R are correct but not directly related causally.
