 Eukaryotes  Have nucleus and membrane bound organelles  Most are unicellular, some are multicellular or colonial  Can be plant-like, fungus-like, or animal- like  Kingdom is considered to be obsolete and will be split into newly designated kingdoms

 EUGLENOPHYTA – Uincellular, have chlorophyll “a” and chlorophyll “b”  Have flagella tht protrude from a gullet and an eyespot that helps them respond to light (phototaxis)  Live in fresh water that is rich with organic material  May exist as autotroph or heterotroph

 Unicellular organisms that live in marine and freshwater.  Have photosynthetic pigments, two flagella and cell walls of cellulose.”  Some produce toxins associated with red tides.

 Includes the golden algae  Most are unicellular, some multicellular  Have photosynthetic pigments, golden color  Cells are covered with tiny scales of silica or calcium carbonate

 Green Algae  Have photosynthetic pigments  Most have flagella at some phase of their lives.  Store food as starch

 Brown algae - Mostly multicellular  Photosynthetic and have chlorophyll “a,b,c” plus carotinoids.  Asexual zoospores and gametes have two flagella.  Includes giant kelps

 Red Algae  Mostly multicellular marine seaweeds.  Have chlorophyll “a and b” and red pigment called phycobillin  Found at great depths  Used in sushi

 Diatoms  Usually non-motile unicellular organisms  Cell walls are in two parts and are made of silica (look like petri dish)

Non-photosynthetic Heterotrophs

 Unicellular protozoa  Move by flagella  Some live in guts of termites Trichonympha  Others are parasitic and cause disease, such as African sleeping sickness, Trypansoma

 Amoeba  Performs phagocytosis by surrounding and engulfing food using pseudopodia (“false feet”)

 Unicellular protists  Have calcareous shells with pores through which cytoplasm extends

 Unicellular protozoans  Move about and feed using tiny hairs called cilia.  Best know is Paramecium, has two nuclei, and oral groove, and contractile vacuoles

 Non-motile parasitic spore-formers  Lack flagella  Amoeboid body form  Include Plasmodium, the malaria parasite  In red blood cells

 “Slime molds” produce large multinucleated masses (plasmodium – different than malaria Plasmodium)  Some have stalks that grow upward and form spores  Other times produce gametes which fuse and produce a diploid zygote that forms the multinucleate mass  Found in moist soil, decaying leaves or logs in a damp forest.
