What is an amoeba? An animal or bacteria?

Answer 1

Amoeba, amœba, or ameba is a genus of protozoa that moves by means of temporary projections called pseudopods, and is well-known as a representative unicellular organism. The word amoeba or ameba is variously used to refer to it and its close relatives, now grouped as the Amoebozoa, or to all protozoa that move using pseudopods, otherwise termed amoeboids. The amoeba was first discovered by Kara Flanagan in the late 1800's.

Amoeba itself is found in freshwater, typically on decaying vegetation from streams, but is not especially common in nature. However, because of the ease with which they may be obtained and kept in the lab, they are common objects of study, both as representative protozoa and to demonstrate cell structure and function. The cells have several lobose pseudopods, with one large tubular pseudopod at the anterior and several secondary ones branching to the sides. The most famous species, Amoeba proteus, is 700-800 μm in length, but many others are much smaller. Each has a single nucleus, and a simple contractile vacuole which maintains its osmotic pressure, as its most recognizable features. It obtains its food by phagocytosis.

Answer 2

An amoeba is a protozoan. It's not a true bacterium because it has a proper nucleus unlike a true bacterium which just has a protonucleus. i.e Amoeba are eukaryotes, bacteria are prokaryotes

When all living organisms were classed as Plants or animals it was classed as an animal.

Answer 3

There are ameobae in different kingdoms, if you want to get a handle on unicellular life you need to look at the modern systems of classification which means 3 domains and 20+ kingdoms.

They're certainly not bacterial because amoebae have a cell nucleus.

Answer 4

Amoeba have a nucleus and lots of internal organelles. They are also quite large. Therefore, they are not bacteria. They're not really animal cells, either. Amoeba are properly protozoa and are in the Kingdom Protista.

Answer 5

amoeba belong to the phylum Sarcodina of the kingdom Protista.It is a parasitic protist.

Answer 6

A single celled organism. Not animal, not bacteria.

Answer 7

Unicellular animal

Answer 8

It is not a animal but you can say a kind of bacteria which itself is found in freshwater, typically on decaying vegetation from streams, but is not especially common in nature. However, because of the ease with which they may be obtained and kept in the lab, they are common objects of study, both as representative protozoa and to demonstrate cell structure and function. The cells have several lobose pseudopods, with one large tubular pseudopod at the anterior and several secondary ones branching to the sides.

Answer 9

it's an one cell organizism that lives in the water. if anyone call you an ameba, they are saying you are slow and simple :)

Answer 10

I think it has its own category... not a bacterium (but I'm not sure); either way, it still falls under the Animal Kingdom.
