If a potato is placed into a 5% sodium solution it looses weight. Why? Explain the direction of water movement and the tonicity of the core and the beaker solution using terms like hypotonic-isotonic-hypertonic
If a potato is placed into a 0% (H20) solution it gains weight. Why? Explain the direction of water movement and the tonicity of the core and the beaker solution using terms like hypotonic-isotonic-hypertonic

1. Describe the changes in your potato sample when placed in distilled water. Based on these changes, was the water hypertonic, isotonic, or hypotonic compared to the cells of the potato? Explain your reasoning in terms of the flow of water into or out of the potato cells. 2, Describe the changes in your potato sample when placed in 0.9% NaCl solution. Based on these changes, was the 0.9% NaCl hypertonic, isotonic, or hypotonic compared to the cells of the...
If a potato core is allowed to dehydrate by sitting in open air, would the water potential of the potato cells decrease or increase
If a potato core is allowed to dehydrate by sitting in open air, would the water potential of the potato cells decrease or increase? i think it decreases but i'm not sure. and if a plant cell has a lower water potential than its surroundings and if pressure=0, is the cell hypertonic(in terms of solute concentration) or hypotonic to its environment? will the cell gain or lose water? any ideas...?http://en.wikipedia.org/wiki/Water_potentialanalysis queswhat is water potential?Osmosis Lab /27819 Name: ________________________________ Date: ___________...

Post-Lab Questions For each of the tubing pieces, identify whether the solution inside was hypotonic, hypertonic, or isotonic in comparison to the beaker solution in which it was placed. Which tubing increased the most in volume? Explain why this happened. What do the results of this experiment this tell you about the relative tonicity between the contents of the tubing and the solution in the beaker? What would happen if the tubing with the yellow band was placed in a...

Potato strips were weighed and then soaked in different salt solutions (0%, 0.9%, and 5% NaCl). After 75 minutes the potato strips were dried and weighed, and the percent change in weight was calculated for each Based on the graph, which salt solution was hypertonic to the potato strips? Which variable is the independent variable in this experiment? The cells in the image are displaying plasmolysis. What type of solution must the cells have been placed into? hypotonic solution hypertonic solution isotonic solution
