BIOL 1201 Chapter : Biology 1201 Chapter 1
Document Summary
About 1. 8 million species have been identified and named, with so many different species there are many different unifying similarities, evolution is a central theme in biology. The ability to evolve is built into organisms. Emergent property is a property that emerges as a result of interactions between components as complexity increases. If you mix all of the components of a chloroplast together in a test tube, photosynthesis will not occur. The molecules must interact in a specific way. Example: sodium + chlorine = sodium chloride: life has the ability to acquire material and energy. All levels of biological organization are thermodynamically open systems . Exchanging energy (heat and work) and matter with their environment (figure 1. 5 from the textbook: structure and function are related. Just as a tool, such as a hammer, is crafted to perform a certain task, the anatomy of plants and animals determine the task that they perform.
