Most living organisms: -Consist of one or more cells -Contain genetic information -Use genetic info to reproduce -Are genetically related and have evolved -Can convert molecules obtained from their environment into new biological molecules -Can extract energy from the environment and use it to do biological work -Can regulate their internal environment Schleiden & Schwann: cell theory -cells are the basic structural and physiological units of all living organisms -cells are both distinct entities and building blocks of more complex organisms. BIG THREE energy transformation reproduce homeostasis autotroph: self feeding; can make organic molecules using inorganic compounds photoautotrophs: use light energy, CO2 to make glucose chemoautotrophs: use chemical energy and CO2 to make glucose heterotroph: different feeding chemoheterotrophs: consume organic molecules for both energy source and C source to transform into other organic molecules photoheterotrophs: use light as energy source but obtain C from food
