The Fourth Unit of Biology is Homeostasis and Transport

The following standards will be covered in this Unit:

• BIO.A.4.1.1 - Describe how the structure of the plasma membrane allows it function as a regulatory structure and/or protective barrier for a cell.
• BIO.A.4.1.2 - Compare the mechanisms that transport materials across the plasma membrane (i.e., passive transport - diffusion, osmosis, facilitated diffusion; and active transport - protein pumps, endocytosis, exocytosis).
• BIO.A.4.1.3 - Describe how the various membrane-bound cellular organelles of the endomembrane system facilitate the transport of materials within a cell.
• BIO.A.4.2.1 - Explain how organisms maintain homeostasis (e.g. thermoregulation, water regulation, oxygen regulation).

Here are the workbook pages for this Unit.  We will be covering sections 8.2, 8.3, and 8.4.
