The Protists
Phytoplankton: Euglena, Volvox, Zooplankton: Amoeba, Paramecium
http://www.dnatube.com/video/5352/Paramecium-FeedingParamecium: unicellular
Nutrition:Heterotroph- oral groove to food vacuole, merges with a lysosome which digests it.
Locomotion:By cilia- covering cell
Respiration/Excretion: by diffusion across cell membrane
Regulation: receptors on cell membrane
Reproduction:Asexual

Nutrition:Heterotroph- phagocytosis forms a food vacuole, merges with a lysosome and digests it
Locomotion:Pseudopodia
Respiration/Excretion:Diffusion through the cell membrane
Regulation:Receptors on cell membrane detect chemicals
Reproduction: Asexual
