An amoeba (/ ə ˈ m iː b ə /; less commonly spelled ameba or amœba; pl.: amoebas (less commonly, amebas) or amoebae (amebae) / ə ˈ m iː b i /), [1] often called an amoeboid, is a type of cell or unicellular organism with the ability to alter its shape, primarily by extending and retracting pseudopods. [2]

Oct 29, 2020 · Amoeba is an aquatic, single-cell (unicellular) organism with membrane-bound (eukaryotic) organelles that has no definite shape. It is capable of movement. When seen under a microscope, the cell looks like a tiny blob of colorless jelly with a dark speck inside it.

Jan 30, 2025 · Amoeba, any of the microscopic unicellular protozoans of the rhizopodan order Amoebida. The well-known type species, Amoeba proteus, is found on decaying bottom vegetation of freshwater streams and ponds.

Apr 8, 2024 · In this article, we will learn about the Habitat, structure, nutrition, characteristics, reproduction, locomotion of the Amoeba cell with diagram. Amoeba cell also known as the ameba or amoeboid. Amoeba is a unicellular eukaryotic organism which can alter their shape by extending and retracting pseudopods.

Feb 26, 2022 · Amoebas are eukaryotes. Their single cells, like those of other eukaryotes, possess certain characteristic features: Their cellular contents are enclosed within a cell membrane, and their DNA...

Oct 4, 2019 · An amoeba is a highly motile eukaryotic, unicellular organism. Typically belonging to the kingdom protozoa, it moves in an “amoeboid” fashion. As such, microbiologists often use the term “amoeboid”, to refer to a specific type of movement and amoebae interchangeably.

Aug 16, 2023 · Amoeba is a single-cell organism, which can change shape accordingly with the help of pseudopodia. They can normally be found in water bodies. In some cases, they succeed to enter into the human body and causing disease. The 18th century offers one of the earliest records describing amoebas.

What is Amoeba? Amoeba is a unicellular organism that has the ability to change its shape. They are usually found in water bodies such as ponds, lakes and slow-moving rivers. Sometimes, these unicellular organisms can also make their way inside the …

Sep 19, 2024 · An amoeba is a type of single-celled organism belonging to the kingdom Protista. Amoebas are characterized by their ability to change shape due to their flexible cell membrane and the presence of pseudopodia, which are temporary projections of the cell. These pseudopodia allow the amoeba to move and capture food through a process called ...

Amoebas are very small single-celled organisms (250-750 microns) known to live in freshwaters, such as rivers, ponds, and lakes. Amoebas use pseudopodia, which are finger-like formations, to move very slowly from one place to another and capture food for consumption. Sometimes, Amoeba can even make it inside the human body and cause diseases.
