Photosynthetic Microbes

1
Photosynthetic Microbes

• Lab 2

2
Algae Spirogyra

• Filamentous green algae
• Found in FW
• 10-100µm
• Spiral chloroplast
• Eukaryotic
• Kingdom Protista
• Phylum Chlorophyta

3
Algae Chlamydomonas

• Unicellular eukaryotic photosynthetic microbe
• Kingdom Plantae but some still consider this a
  protists
• flagellated

4
Diatom Synedra

• Silica cell walls
• Long linear
• FW or Marine
• Photosynthetic
• Kingdom Protista

5
Dinoflagellate Peridinium

• Unicellular eukaryote, photosynthetic
• Kingdom Protista
• Cause algal blooms

6
Moss Chara

• Stoneworts
• submerged aquatic algae of the genus Chara
• FW photosynthetic algae
• encrusted with lime -calcium carbonate deposits
  and have nodes with whorled, filament like
  branches.
• KingdomPlantaeDivisionCharophyta

7
Cyanobacteria Anabaena

• Photosynthetic
• Kingdom bacteria
• Specialized cells to fix nitrogen from the atm
• heterocysts

8
Cyano Nostoc

• Photosynthetic Cyanobacteria
• cells in a gelatinous sheath
• Can be macroscopic
• Kingdom Bacteria
• Heterocysts specialized cells to fix N2 from the
  atmosphere
• Akinetes are resting spores or reproductive
  cell structures that resist dessication and that
  are more granular than heterocysts

9
Cyano Oscillatoria

• Cyanobacteria
• blue green algae
• Gliding movement
• Filamentous
• FW, common

10
Cyano Rivularia

• Filamentous photosynthetic cyanobacteria
• Contain trichomes or strands of filamentous
  algae contained within a sheath.
• cell of each tapered trichome ends as a
  heterocyte that may be followed by an akinete.
• Surrounded by a mucilagenous sheath
