How big can an amoeba get?
Amoeba proteus is a large protozoan, and it can grow up to 1 mm long (average size 250-750 µm). The size ranges based on the amount of food it engulfs. It can almost be seen with the naked eye (still very difficult due to its colorless and transparent body).
Why are amoeba cells so big?
The right image of a small individual of Pelomyxa shows it has hundreds of nuclei. This could enable them to become so big. Apart from the nucleus, the cell may contain water expelling vesicles and all kinds of inclusions (digested food). Many species of amoeba also bear small crystals.
How are humans different from amoebas?
Human beings have complex structures for the complete process of nutrition involving the following steps ingestion, digestion, and egestion of food while Amoeba has a simple process in which it engulfs the food with the help of pseudopodia and traps it in food vacuoles.

How does the shape of an amoeba allow it to become larger than other cells?
An amoeba is a single-celled organism capable of extending itself in various directions and change its shape. The shape changes are facilitated by projecting structures called pseudopodia.
How is amoeba similar to humans?
An amoeba is like a human being because they are both living things made of the same elements, similar macromolecules, and cells.
Humans have 2.9 billion base pairs in their genome, and amoebas (Amoeba proteus) have 290 billion. What is all that extra “information” for? Is it mostly junk?
Is brain eating amoeba rare?
fowleri amoebas are relatively common, they only rarely cause brain disease. N. fowleri disease is known as primary amoebic meningoencephalitis (PAM). It occurs from zero to eight times a year, almost always from July to September.
