Answer 1

The correct option is A Vorticella

• The Vorticella is a protist (protozoan) and belongs to the Phylum Ciliophora.
• It is a very interesting, stalked ciliate with an inverted bell shape.
• The stalk contains a contractile fibril called a myoneme.
• When stimulated, it shortens, causing the stalk to coil like a spring.
• Hence, Bell - animalcule or pedicillate protozoan is Vorticella.
• So, the correct answer is 'Vorticella'.
