Unit 4- Homeostasis and Transport

Homeostasis and Transport


Identify and describe the cell structures involved in transport of materials into, out of and throughout a cell.

  • Describe how the structure of the plasma membrane allows it to function as a regulatory structure and/or protective barrier for a cell.


  • Compare the mechanisms that transport materials across the plasma membrane (i.e. passive transport – diffusion, osmosis,facilitated diffusion; and active transport – pumps, endocytosis, exocytosis).


  • Describe how membrane-bound cellular organelles (e.g. endoplasmic reticulum, Golgiapparatus) facilitate the transport of materials within a cell.


Explain mechanisms that permit organisms to maintain biological balance between their internal and external environments.


  • Explain how organisms maintain homeostasis (e.g., thermoregulation, water regulation,oxygen regulation).
