Identify the asexual reproductive structure ${}^{\text{'}}\mathrm{M}^{\text{'}}$ in the following diagram:

Statement $\left(\mathrm{S}\right):$ In ciliates, conjugation restores the vigour and vitality which are lost due to chromosomal imbalance in the macronuclei due to repeated amitotic divisions.

Reason $\left(\mathrm{R}\right):$ Conjugation is temporary union of senile ciliates belonging to same mating types. It often prevents exchange of nuclear material.

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.
