Document Summary

Photosynthesis: the process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water. Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a byproduct. Plants use this to convert co2 and ho2 to sugars and other organic molecules. Autotrophs: self feeders make their own food. Photoautotrophs: plants and other photosynthesizers are called this because they use energy of light; referred to as producers of the biosphere. Chemoautotrophic: prokaryotes that use inorganic chemicals as their energy source and are the producers in deep-sea vent communities. Heterotrophs: consumers of biosphere; can"t make their own food but must consume plants or animals or decompose organic material. Chlorophyll: what makes leaves green; a light absorbing pigment in the chloroplasts that play a central role in converting solar energy into chemical energy. Mesophyll: green tissue in the interior of the life; where chloroplasts are concentrated.
