Document Summary
When these concepts emerged in the mid 1800s, they established two of the five attributes of life: organisms are cellular, and their populations change over time. The cell theory emerged when robert hooke used a crude microscope to examine the structure of cork from an oak tree: allowed hooke to observe small pore like compartments that were visible to the naked eye. These structures came to be called cells. Anton van leeuwenhoek: after hooke published his work, this guy succecced in developing a much more powerful microscope, capable of magnification of 300x. Cell: a highly orgaized compartment that is bounded by a thin, flexible structure called a plasma that is bounded by a thin, flexible structure called a plasma memberane and that contains concentrated chemicals in an aqueous (watery) solution. The chemical reactions that sustain life take place inside cells. Most cells are capable of reproducing by dividing, by making copies of themselves.
