BIOL 123 Lecture Notes - Lecture 15: Periphyton, Amoeboid Movement, Seaweed
Document Summary
Protists can be informall labeled according to their diverse ecological roles. Can produce organic compounds from inorganic compouds by means of. Feed by absorbing small organic molecules or by ingesting prey. Have bodies, nutrition, or reproduction similar to those of true fungi. Thread like filamentous bodies that absorb nutrients from their environment. Protists can be informally labeled according to their diverse habitats. Usually in moist habitats but more common in oceans, lakes, wetlands, and rivers. Protists that float or swim in fresh or saltwater. Held together with mucilageor short filaments of cells. Many protists live within periphyton- communites of microorganism attached by mucilage to underwater surfaces such as rocks sand and plants. Often produce multicellular bodies such as branched filaments. Photosynthetic protist large enough to see with the unaided eye are called macroalgae or. Protists can be informally labeled according to their type of motility seaweeds. Use pseudopods change shape as they move.
