Document Summary
Chapter 1: biology and the tree of life. An organism is a living entity composed of cells. A theory is an explanation for a general class of phenomena/observations that have a wide body of evidence. Robert hooke was the first to develop a microscope that could magnify 30x. Through his microscopic observations, he could see tiny pores in a cork, which he called cells. Anton van leeuwenhoek refined hooke"s microscope and increased magnification by. He took pond water samples and called the single-celled organisms animal-cules . Cell: a highly organized compartment surrounded by a thin, semi-permeable plasma membrane. Two parts to a theory: pattern: something occurring in the natural world, process: what creates the pattern. Cell theory: all organisms come from cells and cells come from pre-existing cells. At the time, people believed that cells would spontaneously generate. Louis pasteur created an experiment to prove whether spontaneous generation was correct or not.
