An amoeba replicates by splitting in half asexually so that each daughter cell is the same as the parent. Running this process backward from the present, each existing amoeba is the same as its predecessor (fungible) back as far in time as the first amoeba existed. In this regard the amoeba is immortal.
Now it get a bit picky.
The above assumes that no genetic changes have occurred since amoeba #1. This cannot be proved. Replication errors, chromosome damage by radiation etc may have happened to create slightly better or worse (at least different) amoebas that are the ancestors of all amoebas today.
The term "immortal" needs some thought to. No individual amoeba is necessarily immortal. Each amoeba can be killed. Only the amoeba pattern is immortal so far.
Then there is the Star Trek transporter problem. When Kirk is transported he is destroyed at the sending end and reconstituted at the receiving end. Is he the same Kirk? Amoebas are the same. The "mother" amoeba is essentially destroyed as it divides to create the daughters. Do the daughters share all the learnings of the mother? or would they see themselves as unique?

Is amoeba a prokaryote or eukaryote cell and why?
Amoebas are a genus of the Protozoa. They are unicellular, eukaryotic microorganisms, which have one or more nuclei and a contractile vacuole for the purpose of maintaining osmotic equilibrium. They obtain food through phagocytosis, making them heterotrophs. The defining characteristic that makes them eukaryotic, is their membrane-bounded nuclei, which houses they deoxyribonucleic acid.
How is amoeba different from diatom?
An amoeba is a protist and a diatom is not
Why would an Amoeba die if placed in salt water?
Freshwater amoeba in salt water will have a higher solute content outside of the amoeba. The water in the amoeba will want to move out of the amoeba and into the environment. This will cause the amoeba to shrivel and die.
Is an amoeba atrotroph?
No , Amoeba is heterotrophic .
Is the amoeba a algae?
No. The amoeba is a protist.
What is 5 examples of prokaryotes?

What are the Unicellular of the moon?
The Unicellular of the moon is also called microorganisms or microbe. These microorganisms are very diverse. They include bacteria, fungi, archaea, and protists; microscopic plants ; and animals such as plankton, the planarian and the amoeba.
Single celled organisms what are they?
Sinle celled organisms are called "microorganisms". Bacteria are microorganisms with no nucleus. Protists are single celled organisms that are like animals because they have a nucleus. Examples: amoeba, paramecium
When can microorganisms be harmful?
Almost every disease is caused by a microbe. Bacteria, viruses, amoeba, yeast plus many more.
How ameoba take food?
amoeba is a phagocyte. it means that it is a cell which absorbs waste material, harmful microorganisms, or other cells by engulfing them. the process of engulfing food is called phagocytosis.

What is the range of the size of microorganisms?
in bacteria it ranges from 2 micrometer(E.coli) to 1 micrometer in staphylococcus. Some protists are of size upto 300(Amoeba) micrometer and the smallest virus is of size 0.003 micrometer.
Are bacteria and amoeba similar?
An Amoeba is a single cell organism
What animal has one cell?
1) Living things with only one cell are called unicellular organisms. 2) Examples of unicellular organisms are yeast, Amoeba, Paramecium, Euglena and Chlamydomonas. They are also known as unicellular microorganisms because of their tiny size. 3) Amoeba and Paramecium belong to the animal kingdom. 4) Chlamydomonas, Euglena and Pleurococcus belong to the plant kingdom.
