Question

Which of the following is true about nutrition in Paramecium?

A) Paramecium has 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

• Paramecium, a unicellular organism that undergoes holozoic mode of nutrition.
• Paramecium uses its cilia to sweep the food particles from the water and put them into a shallow groove or the feeding apparatus.
• The feeding apparatus of Paramecium has a special name called the vestibulum.
• Paramecium undergoes intracellular digestion. In intracellular digestion, the breakdown of food materials into small molecules occurs inside the food vacuoles within the cell.
• Hence options A, B, and D are the right answers.
