Cell Structure and Functions Unit Plan

Objectives:

1. Describe cell theory and contributions of Schleden, Schwann and Virchow.
2. Understand and describe basic differences of the currently accepted three domains of cellular life and the six kingdoms.
3. Describe the structure and function of the cell components responsible for :
   1. genetic control of the cell.
   2. manufacture of macromolecules.
   3. cellular maintenance
   4. energy processing
   5. support and movement
   6. communication with the intercellular world.
4. Explain that some structures in the modern eukaryotic cell developed from early prokaryotes, such as mitochondria, and in plants, chloroplasts.
5. Describe diffusion and osmosis.
6. Understand how cells act to maintain homeostasis.
7. Explain how surface area to volume ratios affect cell size.
8. Understand importance of membranes to cell function and describe fluid mosaic model.
9. In addition to these basic cellular functions common to all cells, understand that most cells in multicellular organisms perform some special functions that others do not.
10. Understand and explain that, in biological systems, structure and function must be considered together.
