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.
This small protozoan uses tentacular protuberances called pseudopodia to move and phagocytose smaller unicellular organisms, which are enveloped inside the cell's cytoplasm in a food vacuole, where they are slowly broken down by enzymes. Amoeba proteus is very well known for its extending pseudopodia.It occupies freshwater environments and feeds on other protozoans, algae, rotifers, and even other smaller amoebae. Due to phytochromes, A. proteus may appear in a variety of colors (often yellow, green and purple) under a microscope.moeba proteus is very well known for its extending pseudopodia.
