Textbook Question
Chapter 7, Problem 9TYU
SCIENCE, TECHNOLOGY, AND SOCIETY Extensive irrigation in arid regions causes salts to accumulate in the soil. (When water evaporates, salts that were dissolved in the water are left behind in the soil.) Based on what you learned about water balance in plant cells, explain why increased soil salinity (saltiness) might be harmful to crops.

In winter, plants exchange the saturated lipids in their membranes for unsaturated lipids. Unsaturated lipids are "bent" and keep the membranes more fluids because they cannot be stacked closlely together. Of what advantage would this be for herbaceous plants that live through the winter? (Hint: what happens to bacon grease or the grease on top of soup when you put it in the refrigerator?)
You went on vacation and forgot to water your plants. When you returned, the leaves were soft and wilted. Name the organelles that became dehydrated.
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.

Which of the following is true about water movement across cell membranes? A. In a hypotonic solution, cells will swell. B. In an isotonic solution, cells will shrink. C. In a hypertonic solution, cells will stay the same. D. Cells can neither shrink nor swell because water cannot penetrate the plasma membrane.arrow_forward
- Osmosis is a special type of diffusion that ________. a. moves water from an area with a high solute concentration to one of lower solute concentration b. moves sugar from an area with a high solute concentration to a lower solute concentration c. moves water from an area with a low solute concentration to one of higher solute concentrationarrow_forwardIn plants, the cell wall forms as a young plant cell secretes polysaccharides onto the outer surface of its plasma membrane. Being thin and pliable, this primary wall allows the cell to enlarge and change shape. At maturity, cells in some plant tissues deposit material onto the primary wall’s inner surface. Why doesn’t this secondary wall form on the outer surface of the primary wall?arrow_forwardMany fruits can be preserved by candying. The fruit isimmersed in a highly concentrated sugar solution, and thenthe sugar is allowed to crystallize. How does the sugarpreserve the fruit? (Osmosis is a very common phenomenon with fruits)arrow_forward
