BIOL 1202 : BIO LAB Final Study Guide
Document Summary
Likely evolutionary precursors of chloroplasts: unicellular but can grow in colonies large enough to see, photosynthetic and fix nitrogen in aerobic conditions, one of the ultimately producers that feed all other life forms either directly or indirectly. Inhabit extreme environments: phyla within domain archaea, methanogens- no oxygen, extreme halophiles- high salt, extreme thermophiles- high temperatures. Diversity part two: protista: protist are, eukaryotic, unicellular, filamentous, colonial, heterotrophic protists, a. k. a. Trypanosoma african sleeping sickness: mode of locomotion: cilia, phylum ciliophora, most live in freshwater habitats, protective coating over cell membrane called a pellicle (clear, elastic layer of protein, ex. Paramecium: photosynthetic protists- include all algae, except green algae, phylum dinoflagellata, bioluminesce, red-tides, play an important role in primary productivity (photosynthesis), which ultimately provides food for all marine organisms, phylum bacillariophyta, a. k. a. Large leaf-like blades: types of brown algae, ectocarpus, unbranched, filamentous, fucus brown algae, phylum rhodophyta, a. k. a. Live red algae: polysiphonia rhodophyta, filamentous, branched, coralline rhodophyta, branched.
