Document Summary
Evolutionary relationships among species and among cells can be represented by phylogenetic trees: how does one do biology (ask questions, generate hypotheses and predictions, and conduct experiments to test them), living organisms consist of 5 characteristics: A cell is a highly organized compartment bounded by a plasma membrane that contains concentrated chemicals in an aqueous solution. all cells have a plasma membrane. The cell theory states that all organisms are made of cells, and all cells come from pre-existing cells. Within a multicellular individual, all cells are descended from a progenitor cell the zygote. A zygote is also derived from other cells (namely an egg and a sperm cell: essential features of cells: In general, cells contain molecular information (dna) that encodes their physical attributes (through some cells loose their dna). Cells have a boundary between them and the environment. A virus is an agent that infects cells and uses the cellular machinery of a host to replicate.
