Document Summary
Robert hooke created the first microscope and viewed slices of cork, he saw little rooms and called them cellula. Antonie van leeuwenhoek worked with glass, 300x magnification became possible, observed single-celled organisms (protists from pond water, bacteria from his mouth, blood cells, banded pattern in muscle cells, sperm): father of microbiology. Compound microscope magnification and resolution improvement, objects less than 1um. Robert brown botanist, plant cells contained round structures, nucleus is the kernel or. Matthias schleiden used light microscope, all plant tissues composed of cells, embryonic plant arose from single cell. Scientific fact best attempt at stating currently thought fact based on studies, valid until revised/proven wrong with more experiments. Scientific method observations, inductive reasoning to develop tentative explanation (hypothesis) small to large, predictions, controlled experiments, interpret. Theory tested hypothesis many times, in science it"s basically solid ground, biologists rarely use law , but that is the only thing more solid than theory.
