Question

Quizplus · Accepted Answer

Rotifers are similar to paramecia in that they use their cilia for locomotion and for gathering organic matter. However, unlike paramecia which are single-celled organisms, rotifers are multicellular animals. The corona, a ring of cilia around the mouth, is the primary means of locomotion and feeding in rotifers. Option A is incorrect because rotifers are not single-celled protists. Option C is incorrect because ciliates and rotifers are not thought to have given rise to all other animal phyla. Option D is incorrect because both paramecia and rotifers have guts.
