Cyanobacteria
|
a phylum of Eubacteria
-perform plant-like photosynthesis (i.e. cyclic phtophosphorylation plus carbon fixation from CO2) and are thereby considered photoautotrophs -green color from chlorophyll-a (then have no chlorophyll-b) -blue color form phycocyanin -a few species are reddish in color (the color of the Red Sea is from 'blooms' of these cyanobacteria) -carbon fixation produces a storage polysaccharide that is similar to glycogen -internal membarne system with chlorophyll-a is imbedded (thylakoid-like) |
|
|
Oscillatoria
|
kingdom eubacteria
phylum Cyanobacteria (its a genus) -filamentous, filament called a trichome -trichomes composed of individual cells covered by mucous sheath -glides along bottom of lake or slow moving stream by moving the mucus sheath which covers it |
|
|
Anabaena
|
kingdom eubacteria
phylum Cyanobacteria -common in stagnant ponds, filamentous -have heterocysts - regions that fix Nitrogen -some are toxic (neuro & hepato toxins) |
|
|
Kindgom Alveolata
|
Domain Eukarya (select protistan-like cultures and/or slides)
Characteristics: -membranous sacs (alveoli) under the cell membrane |
|
|
Phylum Ciliata
|
Domain Eukarya
Kingdom Alveolata -all move or feed by the use of cilia -usually have rigid pellicle (a thickened cell membrane produced by membrane enfolding) and an oral region or groove |
|
|
Paramecium caudatum
|
Domain Eukarya
Kingdom Alveolata Phylum ciliata |
|
|
Stentor
|
Domain Eukarya
Kingdom Alveolata Phylum ciliata |
|
|
Vorticella
|
Domain Eukarya
Kingdom Alveolata Phylum ciliata -note extracellular stalk rich in contractile filaments (stalk was excreted) |
|
|
Phylum Dinoflagellata
|
Domain Eukarya
Kingdom Alveolata -cell covered with cellulose plates -many have perpendicular grooves that each hold a single flagellum -main photosynthetic pigments are xanthophylls -dinoflagellets are the 2nd greatest producers of organic materials in the oceans |
|
|
Ceratium
|
Domain Eukarya
Kindgom Alveolata Phylum Dinoflagellata |
|
|
Peridium
|
Domain Eukarya
Kingdom Alveolata Phylum Dinoflagellata |
|
|
Stramenopila
|
Domain Eukarya
Kingdom Stramenopila -unicellular or colonial -flagella have a fringe of fine filaments (hairs) in almost all groups |
|
|
Diatom
|
Domain Eukarya
Kingdom Stramenopila Phylum Diatom -fine hairs are lost and no flagellum (they simply float) -classified in the group based upon extensive molecular data -secreted silica scales -chlorophyll -diatoms are the greates producers of organic material in the oceans |
|
|
mixed diatoms
|
Domain Eukarya
Kingdom Stramenopila Phylum Diatom |
|
|
Euglenozoa
|
Domain Eukarya
Kingdom Euglenozoa -photosynthetic flagellates, pellicle usually present |
|
|
Euglena
|
Domain Eukarya
Kingdom Euglenozoa -note the green color (chlorophyll) and the eye spot (region of pigment that aids them orienting toward light) |
|
|
Amoboid group
|
Domain Eukarya
not a kindom polyphyletic -all have pseudopodia that they use for either movement and/or feeding |
|
|
amoeba proteus
|
domain eukarya
amoeboid group |
|
|
Radiolaria
|
domain eukarya
amoeboid group -mixed radiolaria - note the diverse shell morphology of the radiolaria. The pseudopodia project through pores in a shell secreted by each radiolarian cell. |
|
|
Chlorophyta
|
Domain Eukarya
Kingdom Chlorophyta -same photopigmnets as plants (e.g. chlorophyll, xanthophylls, carotenoids) -filamentous or unicellular -have chloroplasts and perform the same form of photosynthesis as plants |
|
|
Closterium
|
Domain Eukarya
Kingdom Chlorophyta -has single chloroplast with pyrenoids (areas of starch deposition) -cell wall bands make the organism look straited |
|
|
Spirogyra
|
Domain Eukarya
Kingdom Chlorophyta -filamentous, each cell in the filament has single helical chloroplast -nucleus very prominent (unstained but amoeba-like) |
|
|
Volvox
|
Domain Eukarya
Kingdom Chlorophyta -large, spherical, semicolonial form -each semi-seperated cell has a flagellum -often filled with daughter colonies (generally produced by mitosis - clones of the mother) |
