    • Algae Quiz (25) Lab quiz: Thursday 11/20 Lab Exam: Thursday 12/6
    • Cellular organization 1. unicellular 2. filamentous: chains of cells attached end to end 3. colonial: groups of algae attached to each other in nonfilamentous manner
    • Chlamydomas • • • • single cell flagella green algae similar to land plants – has chlorophyll a and b – cell walls made of cellulose • stigma
    • Chlamydomas • reproduce via mitosis
    • Cladophora • branched, filamentous
    • syngamy • pairing and fusion of morphologically similar haploid gametes to form a diploid zygote
    • Spirogyra • Spirogyra • Spirogyra is a genus of filamentous green algae of the order Zygnematales, named for the helical or spiral arrangement of the chloroplasts that is diagnostic of the genus. Scientific name: Spirogyra • Rank: Genus • Higher classification: Zygnemataceae
    • Spirogyra • reproduce by conjugation – conjugation tube
    • Volvox • green alga • oogamy • daughter colonies
    • oogamy • motile sperm flows to non-motile eggs to form diploid zygote • Volvox
    • brown alga • • • • • • phylum: phaeophyta fucoxanthin conceptacles oogonia antheridia examples: Macrocytis, Sargassum
    • red algae • phylum rhodophyta • phycobilinds in plastids • Polysiphonia, Porphyra
    • diatoms • • • • phylum bacillariophyta unicellular algae chlorophylls a & c cell wall: silica
    • dinoflagellates • • • • • phylum dinozoa unicellular two flagella red tide bioluminescent • Peridinium
    • dinoflagellates • • • • • phylum dinozoa unicellular two flagella red tide bioluminescent • Ceratium
    • euglenoid • • • • • phylum: euglenida unicellular algae chlorophyll NO cell wall pellicle: made of protein • paramylon granules: food reserves are stored
