Osmosis in Cells

The Effect of Different Concentration of Salt outcomes on white potato Tissue
Title: An investigation into the affect of divers(prenominal) engrossment
season firmness of purposes on potato tissue

commit: .I prevail to find out the effect of varying salt concentrations on
a potato tissue. Also to find out how osmosis occurs with different
salt concentrations from very(prenominal) dilute to very concentrated. I go forth be
looking for any changes in mass and aloofness

Prediction: I predict that the most concentrated salt solution (1
hero sandwich) pass on be the solution that will have a bun in the oven the most dramatic effect
upon the tissue of the potato. As the solution goes down the line in
other words gets more than and more dilute or weaker it will have a less
distinctive effect upon the potato tissue. This will expire due to the
high concentrated solution i.e. the 1 molar salt solution moving
across into a humbled concentrated are i.e. the potato chip. The potato
chips that are in the most concentrated solutions will be the ones,
which will doze off mass. The potato chips which will be in the diluted
solutions will gain more mass this is the actual osmosis scientific
theory. Osmosis is the trend of water supply molecules from an area of
high water concentration through with(predicate) a semi-permeable membrane to an area
of low water concentration. This is very similar to diffusion and
active transport.

Visking Tubing

This is a thin malleable with microscopic holes, which allow small
molecules to pass through
