Unit Overview
Unit Objectives
CED Topic 2.1: Cell Structure -- Subcellular Components
- Describe the structure and/or function of subcellular components and organelles.
- Explain how subcellular components and organelles contribute to the function of the cell.
- Describe the structural features of a cell that allow organisms to capture, store, and use energy.
- Explain the effect of surface area-to-volume ratios on the exchange of materials between cells or organisms and the environment.
- Explain how specialized structures and strategies are used for the efficient exchange of molecules to the environment.
- Describe the roles of each of the components of the cell membrane in maintaining the internal environment of the cell.
- Describe the fluid mosaic model of cell membranes.
- Explain how the structure of biological membranes influences selective permeability.
- Describe the role of the cell wall in maintaining cell structure and function.
- Describe the mechanisms that organism use to maintain solute and water balance.
- Describe the mechanisms that organisms use to transport large molecules across the plasma membrane.
- Explain how the structure of a molecule affects its ability to pass through the plasma membrane.
- Explain how concentration gradients affect the movement of molecules across membranes.
- Explain how osmoregulatory mechanisms contribute to the health and survival of organisms.
- Describe the processes that allow ions and other molecules to move across membranes.
- Describe the membrane-bound structures of the eukaryotic cell.
- Explain how internal membranes and membrane-bound organelles contribute to compartmentalization of eukaryotic cell functions.
- Describe similarities and/or differences in compartmentalization between prokaryotic and eukaryotic cells.
- Describe the relationship between the functions of endosymbiotic organelles and their free-living ancestral counterparts.
