CAS BI 108 Chapter Notes - Chapter 5: Plastid, Proteoglycan, Desmosome
Document Summary
5. 1: cells are the fundamental units of life. Cell theory: cells are the fundamental units of life, all living organisms are composed of cells, all cells come from preexisting cells, evolution through natural selection explains the diversity of modern cells. *implications: body: principles that underlie functions of single cell of bacterium similar to cells of, life is continuous; cells derived from ancestors, origin of life on earth marked by origin of first cells. )thus, cells must be small in volume in order to maintain a large enough surface area- to-volume ratio and an ideal internal volume; surface area (large) enables it to carry out different functions for survival. Division of labor explains complexity of eukaryotes to prokaryotes. Bi108 chapter 5 notes: cells: the working units of life: cytoskeleton: protein filaments that play roles in cell division or in maintaining shapes of cells.
