Question #afac7
1 Answer
Cilia provide motility to paramecium and help them in ingesting food.
Explanation:
Paramecium is a unicellular organism. & belongs to ciliate class of animal-like protists. In paramecium the surface of cell is covered with several thousand fine, short , hair-like structures called cillia.
There are two types of cilia in paramecium i.e
Body cilia:
These cilia beat in such a precisely coordinated fashion that the paramecium can go forward, can also move back and turn around. Thus, these cilia greatly aid organism in motility.
Oral cilia:
These are present on surface of oral groove. Oral groove is sort of crease on cell surface of paramecium which opens into cytosome i.e cell's mouth. Paramecium being unicellular protist has no legs and arms to run around and grab food. So, they rely on these cilia to move them toward their favorite diet i.e mostly bacteria. Oral cilia help to phagocytose the food which then slide into cytosome via oral groove.
