Answer & explanation.
a. The solution inside the cell contains 15% NaCl and 85% water.
b. The beaker contains 35% NaCl and 65% water.
c. The solution inside cell #1 is hypotonic to the solution outside cell#1.
d. The solution outside cell #1 is hypertonic to the solution inside cell #1.
e. out of the cell
g. The water always move from a lower concentration of solutes to a higher concentration until they are equal.
a. The solution inside the cell contains 30% NaCl and 70% water.
b. The beaker contains 30% NaCl and 70% water.
c. The solution inside cell #2 is isotonic to the solution outside cell#2.
d. The solution outside cell #2 is isotonic to the solution inside cell #2.
e. no net movement of water
g. There is equal concentration of solution inside and outside of the cell.
h. remains the same
a. The solution inside the cell contains 50% NaCl and 50% water.
b. The beaker contains 25% NaCl and 75% water.
c. The solution inside cell #3 is hypertonic to the solution outside cell#3.
d. The solution outside cell #3 is hypotonic to the solution inside cell #3.
e. into the cell
g. Since there is higher concentration inside the cell, the water will move into the cell to create equal concentration.
a. Movement of water
- Cell A no net movement
- Cell B into the cell
- Cell C out of the cell
- Cell D out of the cell
b. % Sucrose in Cell
c. Tonicity in Cell
- Cell A isotonic
- Cell B hypertonic
- Cell C hypotonic
- Cell D hypotonic
Answer about Part II:
- There is little to no mass change for the model cell containing solution A because it is isotonic or has equal amount of solute concentration to its environment. B.) Plasma membrane is semi-permeable, meaning only water can pass through and not the solutes hence water moves from a lower concentration to a higher concentration gradient. Since the system is said to be in equilibrium, no net water movement is observed because there is equal amount of concentration in the solutions.
- The water moved into the cell because it contains higher concentration of sucrose than the solution outside the cell.
- The water moved outside cells C and D because both cells contains lower concentration of sucrose than the solution outside.
- Cell C lost water at a faster rate than cell D due to cell C having only 10% sucrose solution, while cell D contains 15%.Â
- Water always moves from a hypotonic solution to a hypertonic solution.
- Hypertonic: lose weight; Hypotonic: gain weight; Isotonic: stay about the same weight
