Homework Answers
1. starch H20 hypotonic outside concentration less compare to inside. Cell plasmolysis means cell weight will increases.
2. Starch Satrach almost isotonic. outside and outside concentration same and maybe extream conc. different count as isotonic.
3. H20 H20 isotonic inside-outside concentration same.Due to absorption cell size changes.
4.H20 Starch Hypertonic solution outside concentration higher compare to inside. Cell size will decrease
5. Starch H20 outside concentration less so lower concentration solute move towards inside and cell size increases.

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...

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...
