Question

question 4 cindy conducts an experiment on diffusion using cells from the imaginary plant b. florensis. she notes that the cells are only made up of sugar and water and the cells contain a 5% sugar solution in them. however, the membranes are only permeable to water. she makes three solutions: pure water, 5% sugar solution and 10% sugar solution. in this experiment, she wishes to see if the solutions will change the mass of the cells in the plant. she places the cells in the solutions and after 20 minutes she makes individual slides of some of the cells from the three solutions, and she views them under a microscope. which of the three solutions is hypotonic to the cells? a the 0% sugar solution (pure water) b the 5% sugar solution c the 10% sugar solution d none of the above

Explanation:

Step1: Understand osmosis and tonicity

Osmosis is the movement of water across a semi - permeable membrane from an area of lower solute concentration to an area of higher solute concentration. A hypotonic solution has a lower solute concentration compared to the cell's interior.

Step2: Analyze each solution

The 0% sugar solution (pure water) has the lowest solute concentration among the three solutions. Water will move into the cells (where there is a 5% sugar concentration) because the 0% sugar solution is hypotonic to the cells. The 5% sugar solution is isotonic to the cells (same solute concentration), and the 10% sugar solution is hypertonic (higher solute concentration).

Answer:

A. The 0% sugar solution (pure water)
