Concept- • Amoeba is a unicellular organism that has the ability to alter its shape. • Grouped under the Kingdom Protista. • Commonly found in water bodies like ponds and lakes. • Based on records amoeboid organism was produced in 1755 by August Johann Rösel von Rosenhof. • The structure of Amoeba consists of cytoplasm, plasma membrane, and nucleus. Explanation- • Amoeba digests its food in the food vacuole. • Nutrition in an Amoeba occurs through a process called phagocytosis where the entire organism pretty much engulfs the food it plans on eating up. • Amoeba pushes out the pseudopodia to encircle the food and engulfs it forming a food vacuole. • The movement of the amoeba is with the help of pseudopodia which forms due to the streaming of protoplasm and the movement of the paramecium is with the help of cilia present all over the body surrounding. • Pseudopodia mean false feet of Amoeba. • Amoeba has a fluid-shaped body, so they can move with the thickness of their skin. • Pseudopodia is the locomotory organ of an amoeba. Thereby the pseudopodia of Amoeba are important for locomotion and feeding
