Question

The false foot in amoeba is known as
A. Pseudopodia
B. Food vacuole
C. Water vacuole
D. None of the above

Answer 1

Hint:
Amoeba is a single-celled protozoan. It exhibits almost all metabolic processes of an organism. It has no shape. Amoeba moves in a crawling manner.

Complete answer:
All living organisms are characterized based on the complexity of their cells, namely, prokaryotes and eukaryotes.
Amoebae are eukaryotes.
Amoeba proteus, the most common species, found on decaying bottom vegetation of ponds and freshwater streams.
Amoeba moves by pseudopodia. Pseudopodia are also used to capture food.
Pseudopodium wraps around the food molecule and forms a food vacuole around it. Food can further be digested with the help of the digestive enzymes secreted in the food vacuole.
Amoeba can move in all directions using false feet called pseudopodia. It can change its shape with the help of these pseudopodia to exhibit locomotion.

Hence, pseudopodia are known as a false foot in Amoeba, Food vacuole and water vacuole are used for the storage of food and water respectively. So, Option (A) is correct.

Additional information-
Pseudopodia cytoplasm filled with the part of the cell wall and have the ability to make a great change in their form to move.
The cells of amoebae, like other eukaryotes, possess certain characteristic features. The cytoplasm and cellular contents are enclosed within a cell membrane. They contain specialized structures called organelles, which execute a range of cellular functions including energy production and protein transport.

Note: Pseudopodia help in locomotion as well as capturing the food. A food vacuole is a storage unit of food for amoeba and it is only formed when the food is engulfed.
The water vacuole or the contractile vacuole, it helps in maintaining the tonicity of the cell. In amoeba, food is taken in and material is excreted on the surface.
