Solution

The correct option is B

Having two types of nuclei


The correct option is B.

The Explanation for the correct option:

Ciliates differ from all other protozoa having two types of nuclei. Ciliates have chair-like appendages called cilia for their locomotion. They are somatic macronucleus and germline micronucleus. Paramecium is an example. The macronucleus is involved in the vegetative functions of the organism and the micronucleus is involved in reproduction.

The explanation for incorrect options:

Option A:

Ciliates don’t use pseudopodia as they have cilia for locomotion and food gathering. Fungi-like protists i.e., slime molds use pseudopodia for movement.

Option C:

Ciliates don’t have flagella they have cilia for locomotion and food gathering. Trypanosoma has flagella.

Option D:

Paramecium, Amoeba, Trypanosoma- these all are freshwater protozoa that have contractile vacuoles. Contractile vacuoles help to move out excess water from the cell.

Final answer: So, ciliates differ from all other protozoa in one aspect- they have one macronucleus and one micronucleus.
