BIOS 208 1st Edition Lecture 1Outline of Current Lecture I. Learning ObjectivesII. Themes: Biological Hierarchy& The Cell Is an Organism’s Basic Unitof Structure and FunctionCurrent LectureI. Learning Objectives A. General Themes in Biology.B. Properties of life.C. Biological Hierarchy…levels of organization from the biosphere to communities, organisms, molecules incells.D. Cell theory, cells as units of life, prokaryotes &eukaryotes.E. Emergent properties.F. Structure follows function.G. Cell division, heritable information as DNA, Genomics.H. Grouping Species.I. Theory of Evolution & Natural Selection.II. Themes: Biological Hierarchy & The Cell Is an Organism’s Basic Unitof Structure and Function A. Life can be studied at different levels, frommolecules to the entire living planet.B. The study of life can be divided into differentlevels of biological organization.C. Biological order: The biosphere, ecosystems, communities, populations,organism,organ system, organ, tissue, cell, organelle, molecule, atoms.D. The cell is the lowest level of organization that canperform all activities required for life.E. All cells -Are enclosed by a membrane and use DNA as their genetic information.F. A eukaryotic cell has membrane-enclosed organelles,the largest of which is usually the nucleus.G. By comparison, a prokaryotic cell is simpler andusually smaller, and does not contain a nucleus or othermembrane-enclosed organelles.H. Emergent properties result from the arrangementand interaction of parts within a system.These notes represent a detailed interpretation of the professor’s lecture. GradeBuddy is best used as a supplement to your own notes, not as a substitute.I. Emergent properties characterize non biologicalentities as well.a) For example, a functioning bicycle emerges onlywhen all of the necessary parts connect in thecorrect
