The Magical World Of Phytoplankton By Aaron Alejandro, Megan Cross and Ben Whitfield

Diatoms Type of phytoplankton Microscopic unicellular eukaryotes, sometimes live in colonies Sessile or motile Size and shape vary greatly

Diatoms Frustule -Cell wall is made of silica Formed by two overlapping valves (like a petri dish) Most live in water, in all types of climates Most are photosynthetic, but some can be heterotrophs Help produce up to 20% of the air we breathe

Dinoflagellates Single celled protist Motile Have multiple flagellum About ½ of dinoflagellates are photosynthetic

Zooxanthellae Cool type of dinoflagellate Has symbiotic relationship with coral

Algal Blooms When algae thrive, large groups of them grow Can result in fish kills

Red Tides What causes a Red Tide? What are the effects of a Red Tide?

PFISTERIA -What is Pfisteria? Is it harmful to humans? What does it have to do with hog farms?
