Question

In the amoeba, water input and output are controlled by the _____. nucleus food vacuole vacuole pseudopodia

Answer 1

The correct answer is vacuole. Vacuole controls the water input and water output of an amoeba. It is found within endoplasm. The vacuole is an essential part of an amoeba because it maintains the life of an amoeba. Malfunction can cause the amoeba to burst.

Answer 2

Answer: The correct answer for the fill in the blank is-  Vacuole.

Vacuole or contractile vacuole is a specialised subcellular organelle that is responsible for osmoregulation ( balance of water and electrolyte concentration).

For instance, in freshwater environment ( which is hypotonic), it allows the water to accumulate inside the cell.

It is predominantly found in protists ( such as Amoeba and Paramecium) and unicellular algae. It prevents the organism from rupturing or lysing as it controls the input and output of water.
