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 .
Protozoa are a diverse group of organisms that are non-phototrophic, unicellular, eukaryotic microorganisms with no cell walls. In general, protozoa have different stages in their lifecycles. Trophozoites are the active, reproductive, and feeding stage.his group can often have complex lifecycles that require multiple host species. Many sporozoans cause disease. Of all the diseases caused by protozoa, the deadliest is malaria, caused by the sporozoan Plasmodium. When a female Anopheles mosquito bites a human, it is able to transmit Plasmodium into the bloodstream.
