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. 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 Chrysophyta (Golden algae and Diatoms)

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

9. Phytoplankton Distribution in Arbutus Lake

10. Phytoplankton Distribution in Catlin Lake

11. 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

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

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