1) When the the sugar concentration increased in the solution, the egg's circumference decreased. This was because the sugar was hypertonic, where the solute concentration(the sugar) was higher, therefore the water inside the cell diffused through the membrane from the high concentration to the low concentration to form an equilibrium.
2) As the external environment changed, the cell's internal environment changed because of the change of the solute concentration. In the vinegar, the solute concentration was less than the egg, so the solvent, the water, entered the cell, passively diffusing through the membrane, in order to create an equilibrium. Then, in the sugar the solute concentration was higher, therefore the water exited the egg, to form an equilibrium.
3) The biological represented in this lab was osmosis, which is a type of diffusion. Osmosis is when water diffuses in and out depending on the solute concentration outside of the cell. When there is a hypertonic solution the solute concentration is higher than the cell's solute concentration, then the cell will shrink due to loss of water. When there is a hypotonic solution the solute concentration is lower than the cell's solute concentration, then the cell grows due to the gain of water.
4) When vegetables are sprinkled with water, they are kept ripe, because the water makes the vegetables isotonic, so that they do not lose water and turn dry. Salt melts the ice because it is hypertonic, so it makes the ice lose water, and melt. When, roadside plants are salted they lose water, due to the hyertonicity,of the salt, making them wither and die.
5) Based on this test I would like to test the results of growing plants with sugar water and vinegar. The vinegar is hypotonic and the sugar is hypertonic, so which one is better for growing plants, and which one would have a worse affect on the plants?
