Question

Which of the following is true about nutrition in paramecium?

• A. Paramecium has a shallow groove called 'Vestibulum' to lead food inside its body.
• B. Paramecium undergoes intracellular digestion.
• C. Paramecium senses food and moves in its direction to be able to engulf it.
• D. Paramecium has holozoic nutrition.

Answer 1

Answer: (A), (B), (D)

The correct options are
A

Paramecium has a shallow groove called 'Vestibulum' to lead food inside its body.

B

Paramecium undergoes intracellular digestion.

D

Paramecium has holozoic nutrition.

There is a shallow groove covered with cilia in paramecium's body. It is the feeding apparatus of the paramecium. It is called vestibulum and it leads food into paramecium's body. As paramecium is also a unicellular organism like an amoeba, all the process of breaking down the food goes into its cell and hence called intracellular digestion. As it also eats his food whole, its nutrition is holozoic.
