Foods high in potassium include potatoes, spinach, beans, lentils, fish, pork, yogurt, bananas, oranges, prunes, peaches and apricots. Tomato products -- in particular, tomato paste and tomato sauce -- are rich in potassium as well.
Historically, protozoa were defined as single-celled organisms with animal-like behaviors, such as motility and predation. The group was regarded as the zoological counterpart to the  protophyta , which were considered to be plant-like, as they are capable of photosynthesis.The terms protozoa and protozoans are also used informally to designate single-celled, non-photosynthetic protists, such as ciliates, amoebae and flagellates.amiliar examples of protists with a pellicle are the euglenoids and the ciliate Paramecium. In some protozoa, the pellicle hosts epibiotic bacteria that adhere to the surface by their fimbriae or attachment pili .
Paramecium aurelia, a ciliated protozoa. Protozoa (in Greek proto = first and zoa = animals) is a diverse group of single-celled, microscopic or near-microscopic eukaryotes (organisms whose cells have nuclei) that commonly show characteristics usually associated with animals, most notably mobility and heterotrophy.rotozoa span several phyla that are generally placed not as part of the kingdom Animalia, but rather as part of the kingdom Protista, sometimes known as the other kingdom or the left-overs kingdom.
