If a plant cell is placed in a salt water solution, where the concentration of water is greater in the solution than in the cell
-Dominant- [34]
Salt reduces the amount of water in a solution, because you're introducing another molecule. If the water concentrations are different, the water is going to want to reach an equilibrium to balance itself out. Because the salt solution has a higher water concentration than the plant cell, the water will move into the cell to try and balance out the concentrations. If the salt solution had a lower water concentration (water potential) then water would move from the cell into the solution.

What are some ways in which the structure of a compound influences its function?
Art [367]
 structure of a compound influences its function in many ways like we take example of phospholipid bilayer  1. The fact that the tails are hydrophobic means that they do not interact with water. When a bunch of phospholipids are floating around in water, they try to arrange themselves in a bilayer that shields the hydrophobic parts from water-based, or aqueous, surroundings.

2. The heads are hydrophilic and can then interact with water and other polar or charged substances on either side of the bilayer. The bilayer acts as a barrier that allows cells to maintain internal conditions that are different from external conditions, which is monumentally important for cells to operate properly. 

3. Phospholipids demonstrate the intersection of structure and function in another way, too. We already know that fatty acids can be saturated or unsaturated and that unsaturated fatty acids have bends in their chains. Those bends prevent fatty acids from packing close.
