Protozoan are organism, usually single-celled and heterotrophic belonging to any of the major lineages of protists and, like most protist, protozoa are microscopic. all protozoans are eukaryotes and therefore possess a true or a membrane-bound nucleus. Examples of protozoa include; Amoeba, Euglena, Paramecium. They exhibit diverse modes of locomotion across the various groups, but the modes of locomotion can be broadly divided into flagellar, ciliary, and amoeboid movement.
"<span>The central vacuole is a cellular organelle found in plant cells. It is often the largest organelle in the cell. It is surrounded by a membrane and functions to hold materials and wastes. It also functions to maintain the proper pressure within the plant cells to provide structure and support for the growing plant."</span>
