QuestionAnswer

F-400• ANSWER: The water potential in a solution

with a pressure potential of 0.25 MPa and a solute potential of -0.75 MPa

• QUESTION: What is -0.50 MPa?

Yw = Yp + Ys = 0.25 MPa + -0.75 MPa =

0.50 Mpa

QuestionAnswer

F-500

• ANSWER: The solute potential of an open container of 0.1 M glucose at 20 oC? (2 decimal places)

• QUESTION: What is -2.43?Ys = -iCRT = -1(.1)(0.0831)(293) = -2.43

QuestionAnswer

FINAL JEOPARDY

• ANSWER: The reason why cells are small

• QUESTION: The surface area-to-volume ratio is larger for smaller objects (esp. as cubes, spheres) than for larger; or volume increases faster than area, so it is difficult to move materials thru and into/out of larger cells.
