Document Summary
Protists- mostly unicellular groups of eukaryotes- very small eukaryotes- as small as many prokaryotes. Some protists are more closely related to plants, fungi, or animals than they are to other protists. The kingdom in which all protists once were classified, protista, has been abandoned, and various protist lineages are now recognized as kingdoms in their own right. Protist- convenient way to refer to eukaryotes that are not plants, animals, or fungi. Protists, along with plants, animals, and fungi, are classified as eukaryotes- in the domain. Eukarya, one of the three domains of life. Unlike the cells of prokaryotes, euk cells have a nucleus and other membrane-closed organelles, such as mitochondria and the golgi apparatus. Such organelles provide specific locations where particular cellular functions are accomplished, making the structure and organization of eukaryotic cells more complex than those of prokaryotic cells. Euk cells also have a well-developed cytoskeleton that extends throughout the cell.
