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.
The primary vacuole functions include maintaining the fluid balance or the internal hydrostatic pressure; exporting the unwanted and toxic substances; acting as a cellular pump; maintaining the cellâs acidic internal pH; and determining relative cell size and even shape, as they can help the cell elongate rapidly.
