Question

The body of Amoeba is made up of ______ cell.
A. Single
B. Multiple
C. Three
D. Four

Answer 1

Hint: Amoeba is a unicellular organism. It can move by the formation of pseudopodia, which is a protrusion of its cell.

Complete answer: An amoeba is a type of cell and it is a unicellular organism that forms with a single cell. It has the ability to alter its shape by outspreading and withdrawing pseudopods, which is also known as locomotory organs of amoeba.
Amoebae is a eukaryotic organism and it is present not only among the protozoa, but also in fungi, algae, and animals.

Additional information: An amoeba can be defined as a single-celled eukaryotic organism, having no definite shape and only moves by means of pseudopodia.
1. Pseudopodia also known as pseudopods are the temporary projections of the cell. The word pseudopod means false feet.
2. The term amoeba or amoeboid is often used to refer to all protozoa that use pseudopodia as their locomotory organ.
3. The word ‘Amoeba’ helps to describe a specific genus of protozoa. Amoeba proteus is the best-known species that belong to this genus. The cytoplasm of an amoeba contains the organelles that are generally in other eukaryotic organisms and those organelles are enclosed by a cell membrane.
4. An amoeba obtains food by a process called phagocytosis. In this process, projections of the cell membrane of the amoeba outspread and surround a food particle and totally enclose it. The food particle is then internalized in the form of a sort of "bubble", in the biological term which is known as a vacuole.
5. The food particle is digested in the vacuole. The amoeba reproduces by binary fission.

So, here the correct answer is option A. Single.

Note: Amoebae can cause disease.
An example includes amoebic keratitis that is caused by Acanthamoeba.
It can also cause amoebiasis and encephalitis in humans.
