Diffusion Activity Summary Worksheet
Date Pd Diffusion Activity Summary Worksheet 1. In the space below draw a story board, at the particle level, representing how the perfume particles moved around the room. Make sure your drawing is based on what you learned in the class discussion. Under the storyboard, explain the process. In this interactive demonstration students will make observations of diffusion of a semi. A teacher's worksheet is. Activities > Diffusion Demonstration.
Original Document: What do you Know? Label the three images below as isotonic/ hypertonic/ hypotonic (with regard to the solution the cell is placed in) Hypertonic.Isotonic.hypotonic 2. Movement across the cell membrane that does not require energy is called active / passive transport. The difference in the concentration of a substance across a space is called a concentration equilibrium / gradient. If there is a concentration gradient, substances will move from an area of high concentration to an area of equal / low concentration.

The cell membrane is selectively permeable / impermeable. Equilibrium / Diffusion is the simplest type of passive transport. The diffusion of water through a selectively permeable membrane is called osmosis / diffusion. The direction of water movement across the cell membrane depends on the concentration of free water molecules / solutions. A solution that causes a cell to swell is called a hypertonic / hypotonic solution.
Organelles that collect excess water inside the cell and force water out are called diffusion organelles / contractile vacuoles 11. The process of taking material into the cell by infolding the cell membrane is called endocytosis / exocytosis 12. In facilitated / molecular diffusion, membrane proteins help molecules across the membrane. In diffusion, molecules spread out / condense 14. The lipid bilayer describes a type of transport / the cell membrane 15. Facilitated diffusion moves substances down their concentration gradient with / without using the cell's energy. STUDY GUIDE 1.
What Is Summary Worksheet
Know the parts of a solution (Solvent and solute) - the solute is the substance this is dissolved (sodium) and the solvent is the liquid it is dissolved in (often water) 2. Label a cell membrane (bilayer, proteins).
