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)
