A) If the potato cells were hypotonic to the surrounding solution, the surrounding solution itself would be what to the potato cells (hypertonic, hypotonic, or isotonic)? B) Were the potato cells submerged in water with no salt hypertonic, hypotonic, or isotonic to the surrounding environment? C) Were the potato cells submerged in 5 g/100mL salt solution hypertonic, hypotonic, or isotonic to the surrounding environment? D) Look at your graph. At approximately what concentration of salt solution would the potato cells have likely been isotonic with the surrounding solution? [Tip: Estimate approximately at what concentration there would have been no change in the average length of potato strips.] dnote -tnote tes On Search Researcher Research (-)…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.Osmosis Practice Activity Osmosis is the diffusion of water from an area of high concentration to an area of low concentration. Only water moves in osmosis! The diagrams below show the concentration of water and salt inside the cell and the concentration of water and salt surrounding the cell.
