Document Summary

Definiton: cell = the vehicle for the hereditary information that de nes the species . > can gather material it needs to sustain growth & replication (make new copies of itself by. Based on ability to actually observe them. Limited by magni cation power of microscope (mad wit dif cult to learn about the internal organization of the cells. Could magnify 30x (was similar looking to current microscope) Had multiple lenses, light sorse, typical column. Lenses, didn"t have magnitude or resolution up to par. Made a simpler microscope but could see 300x. Rst to observe living cells -> animalcules (pond water, sperm, tooth scrapings, etc. ) Mad this own, evidence shows he may have ground down lenses. Heated, stretched, broke glass -> extra thin sphere -> lens. Factors limiting further understanding of the nature of cells: Descriptive nature of 17th century biology (little though given to explaining architectural details. Oe lens magni es the image created by a second lens.
