The Protists Phytoplankton: Euglena, Volvox, Zooplankton: Amoeba, Paramecium
/video/5352/Paramecium- Feeding Paramecium : 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
/watch?v=W6rnhiMxtKU& safe=active Amoeba – unicellular 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
/watch?v=H0TISkBjs7o&sa fe=active Euglena - unicellular Nutrition: autotroph- red eye spot/heterotroph Transport: flagella Respiration/Excretion: diffusion through cell membrane Regulation: receptors on cell membrane detect chemicals Reproduction: asexual
/watch?v=He9FSeGRi3A&s afe=active Volvox- colonial Nutrition: autotroph Locomotion: flagella Respiration/Excretion: diffusion through the cell membrane Regulation: receptors on cell surface detects chemicals in environment Reproduction: asexual- new colonies/sexual- specialized cells
