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.

Properties of Water & Membrane Function
Dr. Isley (a.k.a. Poison Ivy) is teaching a master class on botany. Explain to her the
following concepts so that she will keep her promise to release Batman and Robin
from captivity!
Part 1: Plants absorb water through special cells in their roots. For the water to enter
the root cells, does the water need to be hypertonic, hypotonic, or isotonic to the
inside of the cell? Briefly explain your reasoning?
Part 2: Based on your answer in Part 1, would there be more hydration shells in the
extracellular (surrounding) water or inside of the root cells? (one word answer)
Part 3: First, explain why water is a polar molecule. Then, discuss how the polar
nature of water allows it to form hydrogen bonds with other polar molecules and how
this relates to the ability for water to form hydration shells.

Water will move out of the cell to where there is a lower solute concentration. Water will move into the cell to where there is a lower solute concentration. The cell and solution are in equilibrium, so water will move both directions equally. 76 F Partly sunny arch O O O Oarrow_forward Explain how this relationship between the solution in the Elodea cells (from #1) caused what you observed in the Elodea cells placed in saline solution.arrow_forwardPlease answer the first questionarrow_forward
- 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.arrow_forwardThe plant wall allows for plant cells to swell under large internal pressure, what membrane lined passage allows for rapid movement of polar molecules between cells?arrow_forwardThe membrane in the diagram above is not permeable to the sugar in the solution, however it is permeable to water.

- Observation: I want to know what effect salt has on the growth of grass. So I measure out 3 equal-sized squares of grass out the back of the Green Building. The first square of lawn I water with 5 liters of pure water from a watering can every day. The second square of lawn I water with 5 liters of pure water with 2 grams of salt mixed in, every day. The third square of lawn I water with 5 liters of pure water with 4 grams of salt mixed in, every day. I measure the height of the grass after 14 days and note the following observations. The first square is green and 15 cm high. The second square is greeny-yellow and 6 cm high. The third square is yellowy-brown and looks dead and is only 2cm high. What could we infer about the effect salt has on the growth of grass?arrow_forward"In a beaker containing 6% NaCl, you place a cell which contains 0.9% NaCl. NaCl doesn t cross the membrane.

Scientists have recently learned that mangroves are able to undergo a process similar to reverse osmosis in the tips of their roots. As a result, the water entering the mangrove's body is significantly less salty than the water surrounding its roots. As opposed to artificial reverse osmosis, which uses pressure generated by pumps to force water through a membrane, the mangrove's "passive" reverse osmosis uses negative pressure generated by water evaporating from the mangrove's leaves to pull fresh water through membrane-like structures in its roots. Technology based on the red mangrove's version of "reverse osmosis" is already being developed, and there is hope it may lead to a much less energy-intensive method of desalination (removing salt from water). Develop a potential explanation as to why it would be advantageous to the mangrove to desalinate…arrow_forward
