“Roots grow down and shoots grow up.” That is the conclusion drawn by a group of plant scientists. To validate their results a p
ea seedling was planted as illustrated. A porous pot of water is placed in the soil close to the pea seedling. How would you respond to the plant scientists’ initial conclusion?

B. They are correct. Roots are always negatively geotrophic
C. They are incorrect. Roots are also positively hydrotrophic
D. They are incorrect. Shoots are also positively hydrotrophic
A. They are incorrect. Shoots are negatively geotrophic.

Explanation:
It is a regular occurrence for dialysis bags or dialysis tubing to be employed in permitting smooth movement of molecules when having to do with a fluid. These bags are normally evaluated to ensure that the client has adequate amount in th bag so as to be able to achieve the goal at hand.
If we have five dialysis bags being formed from a semi-permeable membrane which is impermeable to sucrose, they may be saturated with different concentrations of the sucrose with each of these bags being positioned in different beakers that have an initial amount of 0.6 M of a sucrose solution.
At ten minute intervals, the bags were massed and the weight was calculated to look for changes in the level of concentration. In this situation, the bag with the lowest initial concentration of sucrose is be the one that has its mass reducing over time and that is E.
The attached image confirms our answer as from the graph, option E shows the lowest initial concentration of sucrose.
