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 .
1. Protozoa are unicellular eukaryotic microorganisms lacking a cell wall and belonging to the Kingdom Protista. 2. Protozoa reproduce asexually by fission, schizogony, or budding. Some protozoa can also reproduce sexually. 3. Relatively few protozoa cause disease. 4.The vegetative, reproducing, feeding form of a protozoan is called a trophozoite. 5. Under certain conditions, some protozoa produce a protective form called a cyst. 6. Components of protozoa that function as PAMPs include GPI-anchored proteins and mannose-rich glycans.ome protozoa also reproduce sexually by fusion of gametes (see Fig. 1) . The vegetative, reproducing, feeding form of a protozoan is called a trophozoite. Under certain conditions, some protozoa produce a protective form called a cyst that enable them to survive harsh environments.
