A eukaryotic cell has a membrane-bounded nucleus. Cells of this type are found in protoctists, plants, fungi, and animals. Humans are eukaryotes, as are oak trees, mushrooms, and amoebas.
Most eukaryotic algae are autotrophic, but the pigments were lost in some groups. Other protists are heterotrophic, and may present phagotrophy, osmotrophy, saprotrophy or parasitism. Some are mixotrophic. Many protists are flagellate, for example, and filter feeding can take place where the flagella find prey.Other protists can engulf bacteria and other food particles, by extending their cell membrane around them to form a food vacuole and digest them internally, in a process termed phagocytosis.ost eukaryotic algae are autotrophic, but the pigments were lost in some groups.
