Question
Handout: 05 February 2018 Due: 19 Feheuary 2018 2. 2 ps. Given the following setup, describe what will happen over time Assune he Doe sou allows water to pass b 04M 3. 1 pt. Fill in the blanks: A mass balance potometer measures the mass of water that is of the plant, and a bubble potometer measures the water that is the plant. A. inside; mass; leaving B. inside; mass; entering C. entering: mass; leaving D. entering: volume; leaving E. entering; volume; entering F. leaving: mass; leaving G. leaving: mass; entering H. leaving: volume; entering I. inside; volume; below J. None of the above 4. Very briefly describe the results of the mass balance potometer experiment and 2 pts. what this might suggest about plant physiology. (This answer should only be a few sentences long.)Explanation / Answer
Que 2
Ans:
The semipermeable membrane allows water to pass but not solute.
- The diffusion of water down its concentration gradient across a semi-permeable membrane is called OSMOSIS.
- Water is moving from region of higher water concentration (the lower the molarity of the solution, the greater the water content) towards a region of lower water content.
- Over time, the volume of the solution to the right increases and the volume of the solution on the left decreases, as water diffuses from left to right.
