Short/Long Answer
 Explain the rate of transpiration in plants, what affects it, and how
plants have adapted to prevent water loss in various environments.
 Identify how water and molecules will move across a membrane.
Use the comparative terms isotonic, hypotonic, and hypertonic.
Predict what will happen to plant and animal cells in each
environment.
 Predict which tissues and cells would contain certain organelles.
Describe the function of organelles.
 Describe the phospholipid membrane structure. Explain how
molecules can cross the cell membrane. List the types of transport.
 Connect biochemistry and membrane transport to how plants
obtain, transport and release water back to the environment.
 Solve water potential problems. Predict the effect of salts on a
system (relate to water potential). Know what the water potential
formula means and how variation of concentration, pressure,
temperature affect water potential
