Amoeba Meaning: Definition, Examples, and Translations
🦠
amoeba
[əˈmiː.bə ]
Definition
biology, organism
An amoeba is a single-celled organism that can change shape, primarily found in water and moist environments. It belongs to the kingdom Protista and is characterized by its flexible cell membrane and the ability to move and capture food using pseudopodia, which are temporary projections of its cytoplasm. Amoebas can reproduce asexually through a process called binary fission. Some species are free-living, while others are parasitic and can cause disease in humans and animals.
Synonyms
protozoan, single-celled organism.
Examples of usage
- The amoeba moved across the slide in biology class.
- Researchers studied the amoeba to understand its behavior.
- Certain types of amoeba can be harmful to humans.

Interesting Facts
Biology
- Amoebas are found in various environments, including fresh water, salt water, and even soil.
- These organisms reproduce by splitting into two in a process called binary fission.
- They feed by surrounding food particles with their body, a method known as phagocytosis.
Health
- Some types of amoeba can cause diseases in humans, such as amoebic dysentery, which is an infection affecting the intestines.
- Entamoeba histolytica is a specific species responsible for serious health issues, especially in areas with poor sanitation.
Pop Culture
- Amoebas have appeared in various educational cartoons, helping children learn about microorganisms and life in water.
- They are sometimes used in science fiction stories or games as alien life forms due to their unique, shapeshifting abilities.
Science
- Amoebas are often studied in laboratories to understand cell movement and behavior, providing insights into biological processes.
- Their unique ability to change shape and adapt to their surroundings makes them a fascinating subject for scientists.
Origin of 'amoeba'
Main points about word origin
- The word originates from the Greek word 'amoibe', which means 'change' or 'alteration' because amoebas look different as they move.
- It was first used in English in the 19th century to describe these unique organisms found in water.
The word 'amoeba' originates from the Greek word 'amoibe', which means 'change' or 'alteration', reflecting the organism's ability to change shape. It was first introduced into scientific terminology in the 19th century as a descriptor for certain microscopic organisms. The concept of the amoeba has evolved over time with advances in microscopy and cell biology, allowing scientists to study its unique characteristics more closely. The study of amoebas has contributed to our understanding of the microscopic world and the evolution of life, as they are among the simplest forms of life. Over the years, amoebas have also been used as model organisms in scientific research to study various biological processes.
