In March 2011, Campaign Chairman Jim Messina asked a group of 450 top donors to raise $350,000. During the second fundraising quarter of 2011 (the first of the campaign), the campaign raised a record amount of $86,000,000. As of May 3, 2012, Obama and his team have held 130 fundraisers.
A food vacuole is a membrane-enclosed cell vacuole with a digestive function, containing material taken up in by the process of phagocytosis. These are found in amoeba, protozoa, paramecium. In protozoa, whatever the mode of heterotrophic nutrition or diet, the food material is enclosed in food vacuoles, which are bounded by cell membrane. Digestive enzymes are poured into the newly formed vacuole from the surrounding cytoplasm.
Acanthamoeba. An amoeba (also ameba, amoeba amÅba or) amoeboid is a type of cell or organism which has the ability to alter its, shape primarily by extending and retracting. Pseudopods amoebae do not form a single taxonomic, group but are found in every major lineage of eukaryotic. organismsecause the surrounding water is hypotonic with respect to the contents of the cell, water is transferred across the amoeba's cell membrane by osmosis. Without a contractile vacuole, the cell would fill with excess water and, eventually, burst.
