30. Define selectively-permeable membrane:
To be able to:
· Determine the types of solutions plants and animal cells have been placed in if they shrink or swell.
· Determine the direction in which water or molecules will move across a membrane during different methods of transport.
· Know the molecules that can pass freely across the membrane, with a protein channel, and with energy.
· Know that a cell with a higher concentration of salt has a low water concentration. However, it has a high molecule (solute) concentration.
· Know the definition of exocytosis and endocytosis.
· Explain the difference between active and passive transport.
· For bonus: know the functions of organ systems and organelles.
· For bonus: Correct mistakes in an experiment conducted by a student.
