In biology, an organism is any contiguous living system (such as animal, fungus, micro-organism, or plant). In at least some form, all types of organisms are capable of response to stimuli, reproduction, growth and development, and maintenance of homeostasis as a stable whole.
An organism may either be unicellular (a single cell) or, as in the case of humans, comprise many trillions of cells grouped into specialized tissues and organs. The term multicellular (many cells) describes any organism made up of more than one cell.
Scientific classification in biology considers organisms synonymous with life on Earth. Based on cell type, organisms may be divided into the prokaryotic and eukaryotic groups. The prokaryotes represent two separate domains, the Bacteria and Archaea. Eukaryotic organisms, with a membrane-bounded cell nucleus, also contain organelles, namely mitochondria and (in plants) plastids, generally considered to be derived from endosymbiotic bacteria.Fungi, animals and plants are examples of species that are eukaryotes.
Tommy Guerrero (born September 9, 1966 in San Francisco) is an American skateboarder and musician. As a teen, he was one of the prominent members of the Bones Brigade, Powell Peralta's professional skateboarding team that was successful during the 1980s. He was well known for his relaxed style of street skating in his hometown of San Francisco, which was depicted in most of the Brigade's videos (Future Primitive, The Search for Animal Chin, Public Domain, and Ban This). After riding for Powell Peralta, Guerrero and Jim Thiebaud (a hometown friend and PP teammate) started the skateboarding company "Real".
After his success in the world of skateboarding, he decided to pursue his musical interests. Guerrero was a member of the skate rock band Free Beer and the experimental group Jet Black Crayon, but has had more success as a solo artist. His critically acclaimed albums, EPs, and singles combine various types of music from rock, rap, funk, soul, and jazz. In 2004, Rolling Stone magazine named Guerrero's third studio album, Soul Food Taqueria (2003), #2 on its 2003 "best of list".
