Know the Cell Theory, its authors, and its components 3. What is the Theory of Spontaneous Generation; why was it was important in the history of the development of the biological sciences 4. Know the definition of a cell 5. Understand the structural hierarchy of the cell 6. Know the subatomic structures of atoms and understand how these structures produce the unique abilities of atoms 7. Understand how a molecule is formed and the relationship between the atoms involved; know the types of molecules 8. Understand how chemical bonds are formed; know the difference between ionic bonds and covalent bonds 9. Know the four types of macromolecules 4 Topic Objectives 10. Understand the relationship between organelles, cell structure, and cell function 11. Know the two main cell types and be able to describe the differences 12. Know the six kingdoms of living organisms; understand the relationship between the two main cell types and the six kingdoms 13. Know the five criteria used to define a cell 14. Know the basic structure of a eukaryotic cell wall and its primary function in a cell 1. Understand the basic structure of a cell membrane; understand the three mechanisms by which the cell membrane controls the movement of materials into and out of a cell; the three mechanisms include a) passive transport, b) facilitated transport, and c) active transport 5 Development of the Microscope Zaccharias Janssen and son Hans - ~1590 Dutch spectacles makers invented microscope Antonie van Leeuwenhoek Father of the microscope First described microscopic organisms using scope 6 Development of the Microscope Robert Hooke (1660) English physician Cell Biology as a science 7 Development of the Microscope 8 Cell Theory Theodor Schwann 1837 (animals) Matthias Schleiden 1838 (plants) 1. All living organisms are composed of one or more cells 2. Cells are the basic functional units of all living organisms 9 Cell Theory Rudolf Virchow - 1858 3. All cells arise from preexisting cells (biogenesis) 10 Theory of Spontaneous Generation: Abiogenesis Living organisms can arise spontaneously from nonliving material ex. - Frogs from mud - Maggots from meat Francesco Redi 1668 11 Theory of Spontaneous Generation: Abiogenesis Bacteria from meat broth Louis Pasteur 1859 12 13 Definition of a cell The basic subunit of any living system, or The simplest unit that can exist as an independent living system 14 Hierarchy of Cell Structure I.
