Document Summary
Chapter 1: biological tree of life january 6, 2016. Made up of one or more membrane bound units called cells. They store and process informaion that is heritable. As populaion they evolve (change: happens when allele frequency has changed. Cell is a highly organized membrane bounded by a plasma membrane that contains concentrated chemicals in an aqueous soluion, all have plasma membrane. The cell theory states that all organisms are made of cells and all cells come from pre- exising cells. Within a mulicellular individual all cells are descended from a progenitor cell- the zygote: zygote derived from sperm and egg. Cells contain molecular info (dna) that encode their physical atributed (some loose their dna: like rbc. Cells have a boundary between them and the environment. Cells have the ability to harness materials and/or energy. A virus is an agent that infects cells and uses the cellular machinery of a host to replicate.
