Amoeba have pseudopods (AKA ‘false feet’) Flagellated Protozoans. Flagellates have flagella, whip, or tail-like structures which they use to propel themselves through water. WebAsexual reproduction in free-living species usually involves nuclear division and the division of the cell into two identical daughter cells of equal size by binary fission. In parasitic protozoans and some free-living species, multiple fission, resulting in the production of many offspring that may not resemble the parent cell, is normal. During the cycle of …

Web2 de nov. de 2024 · Protozoa and algae are two types of organisms that belong to the kingdom Protista. Protozoa are unicellular, animal-like organisms. Algae are unicellular or multicellular plant-like organisms. Therefore, protozoa are heterotrophs while algae are autotrophs. The main difference between protozoa and algae is their mode of nutrition.
WebPlants most live above water while algae are aquatic organisms.
