Videos of Protista inclusing Amoeba feeding and motion

Videos illustrating topics covered on this site: Protista

	Amoeba in motion from drralfwagner First the colorless ectoplasma moves in front of the pseodopodia, followed by the grained entoplasma. The video is done with the phase contrast technique. Please have a look at my homepage for more: http://www.dr-ralf-wagner.de See: Protista: structure and function: amoeba Amoeba, an introduction
	Amoeba feeding from jsmead The amoeba puts out a pseudopodium and engulfs a small flagellate See: Protista: structure and function: amoeba Amoeba, an introduction
	Spirogyra: conjugation from razor1964 Dr. Jeremy Pickett-Heaps Mallacoota, Australia. Technique: Brightfield www.allthingsscience.com Time-lapse video of the final stages of conjugation. The contents of the cells in one filament flow through the conjugation tube into the cells of the other and eventually form a spore.

	Parmecium eating pigmented yeast from wxfix - Linny Merrybird. The yeast cells have been stained with a dye (Congo red). This doesn't show up until they are grouped together in a food vacuole. The first stage of digestion is acid and the final phase is alkaline. This turns the dye from red to blue. See: Protista: structure and function: paramecium Paramecium, an introduction
	Paramecium moving from wolcottsci Very active paramecium observed in pond water. The magnification is 400X with a digital microscope. From time to time the contractile vacuoles show up and there are brief glimpses of ciliary movement in the oral groove. See: Protista: structure and function: paramecium Paramecium, an introduction
	Paramecium: contractile vacuole from ppornelubio This video has an audio commentary. The feeder channels bring water to the vacuole which then contracts See: Protista: structure and function: paramecium Paramecium, an introduction
	Paramecium feeding from jsmead In the Paramecium static at the base of the screen, the ciliary current in the oral groove can be seen wafting food particles into the cytostome where they accumulate to form food vacuoles. These vacuoles then circulate round in the cytoplasm of the Paramecium. The contractile vacuoles can also be seen, filling and collapsing. See: Protista: structure and function: paramecium Paramecium, an introduction
	Vorticella feeding from EDFWilliams The ring of cilia creates a current a which brings food particles to the oral groove where they form food vacuoles. See: Protista: structure and function: vorticella
	Flagella and cilia from jayaa001 This video has an audio commentary. A mixture of protista using flagella or cilia for locomotion or feeding See: Protista: structure and function
