Important Questions on Modes of Reproduction

MEDIUM
Which one of the statements regarding asexual reproduction is false?
MEDIUM

Statement I: The binary fission of Euglena is called homothetogenic fission because the daughter euglenae are like mirror images.
Statement II: Binary fission in Paramecium is known as perkinetal fission because it occurs at right angles to the kineties.

MEDIUM

Statement (S): In ciliates, conjugation restores the vigour and vitality which are lost due to chromosomal imbalance in the macronuclei due to repeated amitotic divisions.

Reason (R): Conjugation is temporary union of senile ciliates belonging to same mating types. It often prevents exchange of nuclear material.
