Protozoa are single-celled eukaryotic organisms that carry out all life activities within a single plasma membrane. They exhibit diverse shapes and sizes, ranging from flagellated Euglena and Paramecium to amoeboid Amoeba. Many protozoa are symbiotic or pathogenic to plants and animals, including humans, with some causing diseases like giardiasis. They display a wide range of symmetries, forms of locomotion, and means of nutrition, including autotrophy, heterotrophy, and saprozoism.
