Document Summary
Information transfer: information must be transmitted within cells, among cells, among organisms, and from one generation to the next. Energy transfer: life requires continuous input of energy from the sun. Cell theory: a cell is the basic unit of structure in every living thing and all cells come from others. Prokaryotic: exclusive to bacteria and archaea, no nucleus or any membrane-enclosed organelles. Eukaryote: has a true nucleus (unlike prokaryotic) Organisms: respond to physical and chemical changes (stimuli), which then movement is involved. Biological growth: increase in size of individual cells and number of cells, or both: some organisms grow throughout their lives, animals have a growth period that ends at adult size. Development: includes all changes during an organism"s life. (ex: human"s develop from fertilized egg into a multicellular organism with structures and body form adapted to specific functions. ) Metabolism: includes all chemical activities that take place in an organism.
