Document Summary
All organisms are comprised of one or more cells. The cell is the basic unit of life. All cells arise from preexisting cells (heredity: prokaryotic and eukaryotic cells, origins, diversity and model systems, information flow, introduction to nucleic acids. No nuclei (no distinct compartment for dna) Primarily single-celled (some can live in a community, biofilm) Tend to be much more complex than prokaryotes, larger in size and genome. Eukaryotic cell bigger volume membrane bound nucleus nucleolus cytoskeleton framework for moving molecules from one side to another endomembrane: er, golgi body. Plant: same features + chloroplast; vacuole (bc. plants don"t have skeleton, they need a place for storage); cell wall (animal and protostomes don"t have this ) Fossil record show that prokaryotes were present 3 billion years ago and signs of synthesis. Eukaryotes were only found a billion years later. They have similarities and both are in their own way complex. Unlikely that the complex mechanisms are evolved independently.
