what is amoeba?

Answer 1

It is unicellular animal and a micro-organism classified with first type of animals called as PROTOZOA. Presently, It is classified with unicellular Eukaryotic Kingdom called as Protista. It is irregularly shaped and microscopic animal found in waters. The projections of body or cell are called as Psuedopodia meant for locomotion and ingestion of food molecules. It multiplies by simple cell division.

Answer 2

Amoebas, like all protists, are single-celled organisms. The most important part of an amoeba might be the pseudopod (pronounce it "sudopod").

The psuedopod is used to help the amoeba move, and also to eat. It is a part of the amoeba's body that it can stretch out and pull itself with. Or, to eat, the amoeba stretches out the pseudopod, surrounds a piece of food, and pulls it into the rest of the amoeba's body.

Amoebas reproduce (make more amoebas) by a process called binary fission. This means that one amoeba can split in half and make two identical new amoebas.

Amoebas eat algae, bacteria, other protozoans, and tiny particles of dead plant or animal matter.

They spend most of their time attached to the bottom or to plants. Sometimes they float freely in the water. They do this as a "swarm." All the amoebas of the same species will unattach from the bottom or plants and float around until they land in a new place and re-attach.

Animals that eat amoeba include plankton feeders, such as mussels and water fleas.

Answer 3

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.

Early naturalists referred to Amoeba as the Proteus animalcule, after a Greek god who could change his shape. The name "amibe" was given to it by Bery St. Vincent, from the Greek amoibe, meaning change.

A good method of collecting amoeba is to lower a jar upside down until it is just above the sediment surface. Then one should slowly let the air escape so the top layer will be sucked into the jar. Deeper sediment should not be allowed to get sucked in. It is possible to slowly move the jar when tilting it to collect from a larger area. If no amoeba are found, one can try introducing some rice grains into the jar and waiting for them to start to rot. The bacteria eating the rice will be eaten by the amoeba, thus increasing the population and making them easier to find.

Answer 4

A unicellular animal that is commonly found in water. It can also be found under your gum line. There is one called killer amoeba that cause a fatal disease called PAM or Primary Amoebic Meningoencephalitis (which is why it is referred to as PAM).

The move by using a structure called a psuedopodium.

Answer 5

an amoeba is a single cell organism that multiplies by splitting itself in two

Answer 6

Unicelular micro organism.It is the smallest form life.It has no sex.It multiplies on its own through the process of cell division.

Answer 7
