10. What is osmosis? Is it correct to call it the diffusion of water across a membrane permeable only to the solvent, (water), and impermeable to the solutes? Define and understand the terms: isotonic, hypotonic, hypertonic. What are the these conditions on cells with or without cell walls? consequences of
What among the following describes osmosis 1. The diffusion of water from an area low solute concentration to an area of high solute concentration. 2. Osmotic pressure is the force that allows water to move by osmosis through a selectively permeable membrane 3. When a cell is immersed in a hypertonic solution, water enters the cell by osmosis which causes it to swell and eventually burst. 4. A solution with greater concentration of water and low concentratioj of solute isbtermed as hyposmotic
Explain the behavior of water molecules in the isotonic solution.
Osmosis is the diffusion of water, and can be driven by many different factors, including temperature, pressure, the nature of the location, and solute concentration. Which of these is a requirement for osmosis to occur? Water must flow from low to high water potential. Only within plant cells is pressure required. Temperature must be above 30 C. There must be a semipermeable membrane.
3. Draw and label a diagram that demonstrates the difference between tonicity and osmolarity. Be sure to label the new solutions in each condition, draw the changes (if predicted) in cell shape/volume, and clearly use arrows to indicate the movement of water relative to the cell. Please start with a red blood cell in an isotonic solution (Figure D) and show what happens to cell shape and water movement when NaCl (remember that the membrane is permeable to neither of these ions) (Figure E) or urea (a permeable ion) (Figure F).
Which of the following best describes a hypotonic solution? a-There is a higher concentration of solute outside the cell than inside the cell b-There is a lower concentration of solute outside the cell than inside the cell c-The solute concentration both inside and outside the cell is equal d-Through osmosis, water will enter the cell causing it to swell
1. Water movement across a semipermeable membrane and between compartments with differing water activity will occur until acitviites of water in the two compartments become equal. TRUE OR FALSE 2. When there is a difference in water activity between two compartments seperated by a semipermeable membrane. There is net water movement from the compartment with the higher water activity to that with lower water activity TRUE OR FALSE 3. Osmosis requires an attractive force between water and the solute? TRUE OR FALSE
1. Define osmosis, simple diffusion, facilitated diffusion. 2.. Identify why each of these is a form of passive transport. 3. Give examples of each type of passive transport.
In each picture, mark a plus + where the water concentration is higher, and a minus - where it is lower.
18.. Use the following diagram to answer the questions. Assume the membrane is semipermeable to glucose, water, and iodine (IKI). A. Which solutes will diffuse into the cell? B. Which solute will diffuse out of the cell? 10% glucose 40% glucose C. Which solute will not diffuse at all? 20% starch 0% starch D. What type of solution (the outside of the cell - hypertonic, isotonic or hypotonic) does the diagram represent? 70% water 50% water 10% IKI E. What color will the cell be at the conclusion of this experiment? What color will the solution in the beaker be? Justify your answer,
The fluidity of the plasma membrane increases with 1.Increase in unsaturated fatty acids in the membrane 2.Increase in saturated fatty acids in the membrane 3.Increase in glycolipid content in the membrane 4.Increase in phospholipid content in the membrane
Does osmosis occur if a cell is placed in an isotonic solution?
