The four diagrams in Model 2 illustrate movement of four types of substances see the table in Model 1 across a phospholipid bilayer. Use your knowledge of membrane structure and the chemical structures in Model 1 to identify the shapes used in Model 2. Model 2 - The Selectively Permeable Cell Membrane Smaller alle mec.

Model 2 The Selectively Permeable Cell Membrane Outside the cell Inside the cell Small nonpolar or small polar molecules Phospholipid Small surface protein Membrane-spanning protein Carbohydrate chain Glycoprotein Glycolipid 7. What two major types of biological molecules compose the majority of the cell membrane in Model 2. Model 2 The Selectively Permeable Cell Membrane Outside the cell Inside the cell Small nonpolar or small polar molecules Phospholipid Small surface protein Membrane-spanning protein Carbohydrate chain Glycoprotein Glycolipid 7.

What two major types of biological molecules compose the majority of the cell membrane in Model 2. Is clear that the plastic baggie is not permeable to starch but is permeable to iodine. In a cell membrane this is called selective permeability.

In other words the iodine can go through the baggie but the starch cannot. The purpose of this experiment is to show that a cell membrane is a type of barrier and is permeable to some. Selectively permeable means a membrane allows the passage of some molecules or ions and inhibits the passage of others.

The capacity to filter molecular transport in this manner is called selective permeability. The cell model below shows 2 solutions separated by a selectively permeable membrane indicated by the red dashed line. What will most likely occur in this case.

The number of molecules on side A will increase and decrease on side B. The water level on side A will increase but remain the same on side B. Selectively permeable membrane.

A polymeric membrane that permits certain molecules to pass through it by diffusion. Also called semipermeable membrane differentially permeable membrane or partially permeable membrane. A selectively permeable cell membrane is one that allows certain molecules or ions to pass through it by means of active or passive transport.

Active transport processes require the cell to expend energy to move the materials while passive transport can be done without using cellular energy. Model 2 shows a cell bounded by a selectively permeable membrane. There is a sugar solution inside the cell and outside the cell.

Circle the correct responses a. Which side of the membrane has a more concentrated sugar solution. In a concentrated solution there is moreless water.

Which molecules are able to pass through the semi-permeable membrane. The dots because they are small and can fit though the gaps and because they are shown as equally distributed on both sides of the membrane. Model 2 The Selectively Permeable Cell Membrane.

Two selectively permeable membranes allow the baby chick to grow and survive inside the egg. These membranes found just inside the egg shell are crucial because they keep the yolk and cellular. Composed of a phospholipid bilayer with embedded proteins the plasma membrane is selectively permeable to ions and organic molecules and regulates the movement of substances in and out of cells.

Plasma membranes must be very flexible in order to allow certain cells such as red blood cells and white blood cells to change shape as they pass through narrow capillaries. Which types of cells in Model 2 have a selectively permeable membrane. Plant and animal cells both have selectively permeable cell membranes.

Which types of cells in Model 2 have a permeable rigid cell. Certain substances to cross the membrane. The unique functions of cellular membranes are due to their different phospholipid and protein compositions.

Decades of research have revealed these functions. Various models of Plasma membrane. The four historical models of Plasma Membrane are.

Lipid and Lipid Bilayer Model 1925-26 2. 1 Osmosis is the diffusions of water across a selectively permeable membrane. 2Water diffuses across a membrane from the region of lower solute concentration to the region of higher solute concentration.

Water balance of cells without walls. Tonicity is the ability of a solution to cause a cell to gain or lose water. Selectively permeability is a key property of cell membranes.

Membranes that are selectively permeable allow some substances to pass through but not others. Diffusion is the movement of fluid substances from where theyre highly concentrated to where theyre less concentrated. Dialysis tubing is an artificial selectively permeable membrane.

A selectively permeable membrane. A permeable rigid cell wall. The arrows in Model 2 show movement of water into and out of the cells.

What does the thickness of the arrow indicate. 4 POGIL Activities for High School Biology. For each question use diagrams AF in Model 2.

The cell is selectively permeable. Selective permeability means that the cell membrane has some control over what can cross it so that only certain molecules either enter or leave the cell. Molecules can cross the plasma membrane in three main ways.
