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 .
The Protists-Eukaryotic Organisms Kingdom Protista Single-celled, eukaryotic organisms are called protists. They are grouped together in Kingdom Protista. Those protists that are animal-like are put in Subkingdom Protozoa, and the protists that are plantlike belong to Subkingdom Algae.The Protists â Subkingdom Protozoa Members of Subkingdom Protozoa, known as the protozoans, have a cell membrane (the pellicle) but lack cell walls.he Protists â Subkingdom Algae Subkingdom Algae includes all the photosynthetic, eukaryotic protists. Again, they lack the tissue differentiation found in plants. Algae may be unicellular, colonial, or filamentous. Algae have distinct, visible nuclei and chloroplasts.
