BIOL 111 Chapter Notes - Chapter 1: Model Organism, Inductive Reasoning, Deductive Reasoning
Document Summary
Evolution- when an organism adapts to its environment. Biology- study of properties of life (order, evolutionary adaptations, response to environment, homeostasis, reproduction, growth and development) Emergent properties- parts specific to a system that enable it to function as a whole ( ex. parts of the brain, parts of photosynthesis) Reductionism- breaking down a system into individual parts that are easier to study (ex. cell dna, brain prefrontal cortex) Each organisms interacts with the environment in some manner. Global climate change- carbon dioxide accumulating in the atmosphere, melting all the ice caps, global temperature rising. Organisms transform one type of energy to another. Plants: photosynthesis, convert co2 and water to sugar and oxygen. Animals: use sugar as fuel, convert chemical energy to kinetic energy. Energy flows through an ecosystem; enters as light, exits as heat. Cells perform all activity required for life, all cells have some sorts of membrane and dna. Prokaryotic- simple cells, no organelles, bacteria and archaea.
