  1. Phytoplankton and Chlorophyll(Chlorophyll? How about Borophyll?!) By: Kate Hilfanski And Don Maryfiker

  2. What is chlorophyll? • Photosynthetic pigment found in most plants • Able to absorb light and transfer to light energy • Chlorophyll a found in all algae!!

  3. A Little Bit About Phytoplankton • Can be unicellular or multicellular • Very little division of labor • reproduction can be sexual or asexual • Primary producers • food for herbivorous zooplankton (if not toxic) chlamydomonas Volvox

  4. Chrysophyta (Golden algae and Diatoms) • Are eukaryotic • Has pigments chlorophylls a and c and carotenoids • Two Class: • Golden Algae        Ex. Mallomonas • Diatoms -Have frustules made of silica ex.. Fragillaria,Asterionella , and Tabellaria

  5. Cyanophyta (blue-green algae) • Only prokaryotic algae • Has chlorophyll a and phycobilins (phycocyanin -blue-green color pigments) • Some are nitrogen fixers • contain a heterocysts N2 fixation occurs Some are toxic • Examples of members of Cyanophyta: Anabaena or Microcystis

  6. Chlorophyta (green algae) • Are eukaryotic • Have chlorophyll a and chlorophyll b pigments             • It is believed they are the ancestors of higher plants Examples: Spirogyra,Pediastrum, and Volvox

  7. Pyrrophyta (dinoflagellates) • Are also eukaryotic • Have chlorophylls a and c and xanthophylls pigments Example: Ceratium

  8. Phytoplankton Distribution in Arbutus Lake

  9. Phytoplankton Distribution in Catlin Lake

  10. Phytoplankton Distribution in Green Lake • There were many cyanobacteria but only one synura in the Chemo layer • Phytoplankton was not found in the other layers

  11. Phytoplankton Distribution in Oneida Lake • Aulacosira dominated meta and hypo but small flagellates dominated the epi

  12. Phytoplankton Distribution in Onondaga Lake Microcystis dominated all layers. LGRB was found along with microcystis in all layers
