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 human body and cause various illnesses.
- One of the first reports referencing amoebas dates can be traced back to 18th century. A German naturalist named August Johann Rösel von Rosenhof who discovered a specimen and made detailed illustrations of the same in 1755.
Structure of Amoeba:-
Typically, most amoebas are characterized by the following features:
- Movement occurs through the use of pseudopodia, where the cytoplasm pushes the plasma membrane outward or inward, creating blunt, finger-like projections.
- There can be multiple pseudopodia at one particular instance, hence, its shape rapidly changes.
- Structure of amoeba primarily encompasses 3 parts – the cytoplasm, plasma membrane and the nucleus.
