BIOL 1081 Lecture Notes - Lecture 38: Karyogamy, Termite, Heterokaryon
Document Summary
Protists & fungi reading: sections 28. 1, 28. 6, 31. 1-31. 3, 31. 5 in textbook: define what protists are and describe their evolutionary, structural, and ecological diversity. Protists: eukaryotes (domain eukarya) that are not plants, animals, or fungi. Eukaryotic cells have a nucleus and other membrane-enclosed 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. Eukaryotic cells have a well developed cytoskeleton that extends throughout the cell. This cytoskeleton provides the structural support that enables eukaryotic cells to have asymmetric (irregular) forms, as well as to change in shape as they feed, move, or grow. The organisms in most eukaryotic lineages are protists, and most protists are unicellular. Structural diversity: most protists are unicellular, although there are some colonial and multicellular species. At the cellular level, many protists are very complex- the most elaborate of all cells.
