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 /), 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.

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 human body and cause various illnesses.
They are freshwater organisms found at the bottom of ponds and streams in the decaying vegetation. They can be identified by their shape changing ability from their cytoplasmic extensions called pseudopodia. Read this article to find a well-labelled diagram and features of amoeba.
Nutrition in Amoeba. Nutrition in an Amoeba occurs through a process called phagocytosis where the entire organism pretty much engulfs the food it plans on eating up. The mode of nutrition in amoeba is known as holozoic nutrition. It involves the ingestion, digestion and egestion of food material. 11,053.
An amoeba is a one-celled creature that is among the simplest of all living organisms. Most amoebas are so small that they can only be seen though a microscope. There they look like tiny blobs of colorless jelly. Amoebas are found in fresh and salt water.
Structure, Classification, Examples, and FAQs of Amoeba. All living beings on the earth are made up of structures called cells. Down at the microscopic level, this is the very basis of life. Every organism, including humans, begin their lives as a single cell and then branch into millions of these cells.
Ameba is a type of single-celled organism capable of changing its shape in different environments. Based on the Bi-directional Evolutionary Structural Optimization (BESO) technique originally proposed by Professor Yi-Min (Mike) Xie, his team at XIE Technologies has developed a topology optimization software tool called Ameba.
An Amoeba obtains its food by phagocytosis, engulfing smaller organisms and particles of organic matter, or by pinocytosis, taking in dissolved nutrients through vesicles formed within the cell membrane. [14] Food enveloped by the Amoeba is stored in digestive organelles called food vacuoles .
Feb 6, 2023 · Its function is to regulate the water content of the cell. Since Amoeba proteus is a unicellular organism, the water molecules can freely flow in or out through the semi-permeable cell membrane via osmosis. When Amoeba proteus moves to a place with fewer ions (minerals), the environment becomes hypotonic to the cell.
