-Protist cells may contain a single nucleus or many nuclei; they range in size from microscopic to thousands of meters in area. Protists may have animal-like cell membranes, plant-like cell walls, or may be covered by a pellicle.
-On a paramecium's exterior is found the pellicle. The pellicle is stiff to maintain the paramecium's shape and provide stability but it is also flexible to allow movement. It also acts as an attachment site for external organelles such as cilia.
Malaria is the most significant parasitic disease of human. The disease is caused by protozoan of the genus Plasmodium. The most serious malignant malaria is caused by<em>Plasmodium falciparum.</em> It is transmitted by the female Anopheles mosquito. Plasmodium is a protist that cause malaria. Different types of species of the plasmodium are: P.vivax, P.malaria, P.ovale and P.falciparum which causes the most serious malignant called malaria.
Protist have animal-cell like membrane and is plasmodium is the example of protist. Its contain single nuclei or many nuclei. On a paracium exterior found a pellicle. Pellicle is a layered structure which surrounds the cells in many types of protozoa and also surrounds the cytoplasm. It is the non-extracellular like the cell wall of plants.
