Lab 2 Diffusion Osmosis Lab Report v2

Osmosis Practice Activity Osmosis is the diffusion of water from an area of high concentration to an area of low concentration. Only water moves in osmosis! The diagrams below show the concentration of water and salt inside the cell and the concentration of water and salt surrounding the cell. Complete the sentences below by comparing the concentration of the water inside the cell and the concentration outside the cell. 1. a. Water will flow the cell, out of the cell, in both directions). (into 5% NaCl 95% H20 95% NaCI 5% H20 b. The cell will (shrink, burst, stay the same). a. Water will flow (into the cell. 2. 5% NaCl out of the cell, in both directions). 5% NaCl 95% H20 95% H20 b. The cell will (shrink, burst, stay the same).

Diffusion and osmosis classification Classify the following characteristics based on whether they are describing diffusion, osmosis, or both. Diffusion Results in an Can occur with equal distribution of solute molecules or without a membrane Always involves the movement of water Requires a semi-permeable membrane Osmosis Involves the movement of gases, ions, and small water soluble molecules Passive form of movement that requires no energy Moves from areas of high concentration to low Both Diffusion and Osmosis Responsible for gas exchange in the lungs concentration A 3 of 15 Next > Cation to open the document "Epicinstaller-13.0.0-fortnite-a8e4f12cada646caa706d8be407be69f (3).msi". tv 22

Link each process with the correct definition. RECEPTORMEDIATED ENDOCYTOSIS PHAGOCYTOSIS PINOCYTOSIS EXOCYTOSIS 1. A cell ingests a large particle, such as a bacterial cell. 2. Receptor proteins embedded in the membrane recognize specific surface characteristics of substances. 3. A transport vesicle inside the cell approaches the plasma membrane of the cell, fuses with it, and releases its contents to the outside of the cell. 4. A vesicle containing whatever molecules are in solution outside the cell bulges inward, pinches off, and enters the cell.

Cells transporting substances across their membranes is essential. Choose TWO of the following types of cellular transport. ๏osmosis ๏active transport (b)Using the same transport types, identify a specific cell that utilizes that type of transit (i.e. one cell for each transport type, or two different cell examples), and detail a substance that is transferred. (c)A typical human lymphocyte has a radius of about 10 μm, while a typical bacterium (e.g., S. pneumoniae) has a radius of about 1 μm. Assuming that both cell types are perfectly spherical, compare and contrastthe transport mechanisms for each of these cells.

The classic demonstration that cell plasma membranes are composed ofbilayers depends on the following kinds of data:• The membrane lipids from 4.74 x 109erythrocytes will form a monolayer of area 0.89 m2when spread on a water surface.• The surface of one erythrocyte is approximately 100 μm2in area. Show that these data can be accounted for only if the erythrocyte membrane is a bilayer.
