What Is the Structure of an Amoeba?

An amoeba is a single-celled microorganism with a cytoplasm, nucleus, cell membrane and several other organelles that perform the functions required for it to be considered a living thing. This type of microorganism belongs to the Protista kingdom. According to the website TutorVista.com, Amoebas are found in moist or wet areas and even inside animals.

Amoeba is defined primarily by the fact that it consists of a single cell. Because it must sustain itself using only a single cell, an amoeba has many different organelles. Amoebas have cell membranes that allow them to change shape and absorb substances. Their movement is facilitated through the use of pseudopoodium. Their cytoplasm is the home to their chemical reactions. Amoebas use their cytoplasm to consume food. Like all cells, the nucleus of the amoeba keeps and copies its genetic material and allows it to perform cell reproduction. When amoebas replicate, their daughter cells are identical to the original.

Additionally, amoebas have several vacuoles that digest food and remove water and digested microscopic organisms. Because amoebas have a tendency to absorb more water than they need, they must regularly dispose of any excess water that has accumulated inside of the threshold of the cell membrane.
