10% salt in a cell in 90% water |
10% salt in a cell in 15% sugar solution
Ans. Hypertonic solution is that solution that has higher osmotic concentration as compared to the cell sap concentration.
Isotonic solution:- It is that solution that has same osmotic concentration as that of cell sap concentration.
Hypotonic solution:- It is that solution that has low osmotic concentration as compared to that of the cell sap concentration.
A. The cell is hypotonic to the 25% NaCl solution.
B. The cell is hypertonic to pure water.
C. The cell is hypertonic to 90% water solution.
D. The cell is hypotonic to 15% sugar solution.

Read the label on the 0.9 % Sodium Chloride IV solution bag. 1. What is the osmolarity of this solution? Is this solution isotonic, hypertonic or hypotonic? Explain. 2. Is the stated...
Choose to put a red blood cell in a hypotonic, hypertonic, or isotonic solution, what is the effect on the RBC? Why is tonicity important in clinical practice?
1) Draw (using dots to represent solute) a hypertonic, hypotonic, and isotonic relationship across a membrane. Which way is water moving in each relationship? 2) Draw plant cells in hypertonic, hypotonic, and isotonic solutions. What happens to each plant cell when placed in each solution? 3) Draw animal red blood cells in hypertonic, hypotonic, and isotonic solutions. What happens to each plant cell when placed in each solution? Thank You!
3. Classify each saline solution as isotonic, hypotonic, or hypertonic (compared with the inside of blood cells). The serum sample shows what the blood cells look like under normal conditions in the bloodstream. Classification Solution 0% NaCl 1% NaCl 10% NaCl
