Biology Reading for 2/20/15StramenopilesStramenopiles: One major subgroup oof the SAR clade that includes some of the most important photosynthetic organisms on the planet. Their flagellum has numerous fine, hairlike projectionsThe three groups of stramenopiles: Diatoms, golden algae, brown algaeDiatomsDiatoms: unicellular algae that have a unique glass-like wall made of silicon dioxide embedded in an organic matrixThey can withstand pressures as great as 1.4 million kg/m2Golden algaeGolden algae: Typically biflagellated with both flagella attached near one end of the cell. Have yellow and brown carotenoidsBrown algaeBrown algae: the largest and most complex algae. All are multicellular. Have brown or olive colored carotenoids in this plastidsHoldfast: a root like structure that anchors the algaStipe: a stem like structure that supports the bladesBlades: a leaf like structure of a seaweed that provides most of the surface area of photosynthesisAlign: gel-forming substance that is used to thicken many processed foodsAlternation of generationsAlternation of generations: the alternation of multicellular hyploid and diploid formsSporophyte: the diploid individualHeteromorphic: the sporophytes and gametophytes are structurally differentIsomophic: The sporophytes and gametophytes look similar but differ in chromosome numberAlveolatesAlveolates: have membrane-enclosed sacs under the plasma membraneDinoflagellatesDinoflagellates: A member of a group of unicellular photosynthetic algae with two flagella situated in perpendicular grooves in cellulose plates covering the cellApicomplexansApicomplexans: a protest in a clade that includes many species that parasitize animalsQuizlet link: http://quizlet.com/72007059/biology-reading-for-22015-flash-cards/Works citedWasserman, Reece, Urry Minorsky, and Cain Jackson.
