Chapter 7.3, Problem 9ELO
Summary Introduction
Introduction:
Movement of water molecule through a semi-permeable membrane in two solutions of varying concentrations is known as osmosis. Depending on the direction of movement of water types of osmosis may be categorized.

1. Clearly distinguish between the terms diffusion and osmosis.
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

- 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).arrow_forward6. If it can cross a membrane, a solute will move from a hyposmotic/hyperosmotic (circle or highlight the correct one) solution to a hyposmotic/hyperosmotic (circle or highlight the correct one) solution.arrow_forward1.

(Keywords: transport of 2 potassium ions to the cytosol, import of 3 sodium ions outside of the cell; establishment of electrochemical gradient; use of active transporter which utilizes energy to transport ions against the gradient)arrow_forward8. When solutes move across a semipermeable barrier from areas of high concentration to low concentration: it requires energy input. it requires no net energy input. it causes the water to go up. the total solute concentration increases.arrow_forward24.
