(vii) Geotaxis (response to gravity): Amoeba Proteus exhibits positive geotaxis since it moves toward the centre of gravity like other animals. Scientific studies are ongoing to classify Amoeba by using small subunit ribosomal RNA (SSU rRNA) genes. The pseudopods are extensions of the cytoplasm. During adverse environmental periods many amoebas survive by encystment: the amoeba becomes circular, loses most of its water, and secretes a cyst membrane that serves as a protective covering.

During feeding, extensions of cytoplasm flow around food particles, surrounding them and forming a vacuole into which enzymes are secreted to digest the particles. In the body of Amoeba, carbon dioxides are produced by the metabolism of fats and carbohydrates, whereas ammonia are produced by the metabolism of protein.

Amoeba proteus taxonomy: taxonomy/phylogenetic: Arctos Specimen Database: Amoeba proteus (Pal.) Amoebas are identified by their ability to form temporary cytoplasmic extensions called pseudopodia, or false feet, by means of which they move about. Amoebas are used extensively in cell research for determining the relative functions and interactions of the nucleus and the cytoplasm. order Amoebida family Amoebidae genus Amoeba ...
