The Factors Affecting Osmosis in Potato Tissue

Factors influencing the infiltration of potato tissue In this course, I am studying factors that affect the penetration of potato tissue. [Image] Penetration is defined as the net motion of water molecules from high concentration region to low concentration region. This motion must pass through a partially transmissive membrane, such as a cell membrane, which allows smaller molecules such as water to pass through but not larger molecules.

What I change will be the concentration of the solution that will help you study the penetration of potato tissue, in the investigation of the independent variables (what you change) and the factors that affect penetration. When potatoes were placed in sugar solution placed at different molarity (strength), different sugar concentrations were changed to observe potato results. Dependent variable (what you measure) In this permeation experiment it is measured the change in mass and length of potatoes in different molar concentrations of sugar solution. Record the mass in grams and change the length using a ruler.

Invasion is the entry of water molecules from a weak solution through a partially permeable membrane into a stronger solution. In this case, a small hole in the potato membrane allows water molecules to enter and exit the solution and potato depending on the concentration gradient of the two substances. Therefore, in this case, if the water concentration in the tissue is low, the water will enter the potato tissue and the potato will be of good quality. If the concentration difference between the two water is small, the quality does not change very much. Furthermore, if the potato contains a higher concentration of water, the osmotic action is the transfer of water molecules from the high concentration zone through the partially permeable membrane to the low concentration zone so that the water flows out of the potatoes and enters the solution.
