Today’s Objectives

Vocabulary These should be done by test day!  plasma membrane (see 7.1)  selective permeability  phospholipid bilayer  transport protein  fluid mosaic model  diffusion  dynamic equilibrium  facilitated diffusion  osmosis  isotonic / hypotonic / hypertonic  active transport / passive transport  endocytosis / exocytosis

Facilitated Diffusion Definition: -movement of materials across the cell membrane using proteins Channel ProteinsCarrier Proteins

Isotonic Solution -Water and dissolved substances diffuse into and out of the cell at the same rate Plant Cell

Hypotonic Solution -Solute concentration is higher inside the cell -Water diffuses into the cell Plant Cell

Hypertonic Solution -Solute concentration is higher outside the cell -Water diffuses out of the cell Plant Cell

EXIT FILL-IN: level of understanding of today’s objective   EXIT: List the different types of Passive transport and give brief explanations for each.
