Question
What is the dependent variable of the experiment?
The term hypertonic describes a solution which has more solute (salt) and less solvent (water) than the cell. In this case the cell will lose water. However, after watering the plant, the cells become re-inflated with water and the plant Osmosis is the process where water moves across a selectively permeable cell membrane by diffusion. Water moves from the solution with more water to the solution with less For example, if you place a red blood cell in pure (distilled) water, it will quickly take up Pre-Lab: Osmosis water. The process of osmosis muşt be tightly controlled by cells, otherwise they will die. water until it bursts. That is why plasma, the liquid portion of our blood is made of water with proteins and salts dissolved in it, preventing the unnecessary gain of water by our In plants, osmosis is just as important. Plants with too little water will wilt. This happens when water moves out of the cells by osmosis.

C. Plant cell placed in a salt solution greater than the concentration inside the cell, This cell will lose water as the water moves by diffusion from higher to lower concentration. In this lab activity you will observe the effects of osmosis on plant cells. You will use the weight of cubes of potato to see how much water moves in and out of cells in different salt solutions.

Expert Solution
Step 1

A variable is any characteristic, numbers, or quantity that can be measured or counted. A variable is also called data item. Number of books, weight of book is variable. In variables the values may change more then once over the time period.
