Document Summary
Life: movement, metabolism, reproduction, response to environment. Robert hooke: coined term cell while viewing cross-sections of cork in primitive light microscope. Anton van leeuwenhoek: viewed animalcules in pond-water and bacteria in scraping from his teeth. Schwann & schleiden: all organisms are composed of one or more cells, the cell is the structural and functional unit of life. Virchow: cells can arise only by division from a pre-existing cell. Spontaneous synthesis of organic molecules probably provided the basic materials from which the first living organisms arose: the spontaneous formation of organic molecules was first demonstrated by. Only molecule able to both catalyze chemical reactions (ribozyme), and self replicate (through nucleotide base pairing). Likely the first genetic material in an early stage of chemical evolution leading to formation of primitive cells. In present day cells, dna is the genetic material, rna is the carrier of information, and proteins carry out most functions.
