Need an elementary definition of Osmosis.....?

Osmosis is a special type of diffusion that only water can do.In a area of high water the water will move to a area of low water! Definition is....osmosis is a form of diffusion were water moves from a region of high water concentration to a region of low water concentration across a semi-permeable membrane!

Because of osmosis (the diffusion of water through a membrane) the water will move from the higher concentration of water to the lower concentration of water. (From the solution with less sugar, to the solution with more sugar, because it has less water in it with the sugar taking up the space.)

O = the concentration of salt in the ocean.\nS = the concentration of salt in  sweet water\nB = the concentration of salt in our blood.\nO - B < S - B. That's why.

A Hypotonic solution is one in which the concentration of electrolyte is below that in cells. In this situation osmotic pressure leads to the migration of water into the cells, in an attempt to equalize the electrolyte concentration inside and outside the cell walls. If the difference in concentration is significant, the cell walls may rupture, leading to the death of the cell. Consequently, it is vital that the electrolyte concentration of liquids used during blood transfusions be matched to that in cells.

Osmosis is the movement of water across a barrier.  Diffusion is the movement of other molecules, not necessarily across a barrier. Check out - \nhttp://www.madsci.org/posts/archives/feb2000/951455351.Cb.r.html for a more detailed answer on what diffusion is compared to osmosis.

The amobea will shrivel and die.  Osmosis causes solutions to find equalibriam by moving from places of high concentration to low conetration.  Because the solution of saline in the water is high there is a lower concentration of free H2O that that in the cytoplasm of the amobea; thus the H20 from within the amobea will move, throgh the membranous cell wall trying to create a balance where both bodies (saline solution and cytoplasm) have equal parts sodium and H2O\n\nleave the kid be...if you had this stuff when you were in school you would have used the hell out of it.   Don't pretend you wouldn't...Besides...it is a valid research tool...qualitative research.

transpiration refers to the evaporation of water from plants.\n\nwater in ground -> pulled by plant's roots through osmosis -> water moves through inner layer of dermal cells -> water from cell membranes move into the xylem (which is the root's core) -> water moves into leaf cells -> water exits though the stomata after being vaporized by heat

Cell walls surround the cell outside of the plasma membrane.  When water flows into the cell by osmosis, the cell swells until its membrane builds up pressure against the cell wall.  The cell wall prevents the cell from swelling and bursting in a hypotonic solution.

Ok so the equation for osmotic pressure is:\n\npi = iMRT\npi = Osmotic Pressure\ni = i-factor\nM = Molarity\nR = Gas Constant (0.08211 L*atm / mol*K)\nT = Temperature (in kelvin)\n\nNow you know MRT because of what they give you but you need to find the value of the i-factor. The i-factor is the van 't hoff factor and is equivalent to the number of molecules associated or dissociated from the original solute. Since K2SO4 dissociates into 2 K+ ions and 1 SO4 2- ion, then the i-factor is 3.\n\nTherefore, plug in the numbers and solve.\n\npi = 3(0.250 mol/L)(0.08211 L*atm / mol*K)(318K)\npi = 19.6 atm

Osmotic pressure is the hydrostatic pressure produced by a solution in a space divided by a differentially permeable membrane due to a differential in the concentrations of solute.\n\nOsmotic potential is the opposite of water potential with the former meaning the degree to which a solvent (usually water) would want to stay in a liquid.\n\nWhen a biological cell is in a hypotonic environment (the cell interior contains a lower concentration of water than its exterior), water flows across the cell membrane into the cell, causing it to expand due to osmotic pressure. In plant cells, the cell wall restricts the expansion, resulting in pressure on the cell wall from within called turgor pressure. The osmotic pressure π of a dilute solution can be calculated using the formula\n\n\nwhere\ni is the van 't Hoff factor\nM is the molarity\nR is the gas constant, where R = 0.08206 L atm/mol K\nT is the thermodynamic temperature (formerly called absolute temperature)\n\nNote the similarity of the above formula to the ideal gas law and also that osmotic pressure is not dependent on particle charge.\n\n[edit]\nApplications\n\nOsmotic pressure is the basis of reverse osmosis, a process commonly used to purify water. The water to be purified is placed in a chamber and put under an amount of pressure greater than the osmotic pressure exerted by the water and the solutes dissolved in it. Part of the chamber opens to a differentially permeable membrane that lets water molecules through, but not the solute particles. The osmotic pressure of ocean water is about 27 atm. Reverse osmosis desalinators use pressures around 50 atm to produce fresh water from ocean salt water.\n\nOsmotic pressure is necessary for most plants. It is the resulting turgor pressure on the cell wall that allows herbaceous plants to stand upright, and how plants regulate the aperture of their stomata. In animal cells which lack a cell wall however, excessive osmotic pressure can result in cytolysis.

I assume this is based on the principle of Osmosis. I would like a bit more data before answering further.

The layman's term I always heard was "learning by osmosis."

Osmosis is the passage of water from a region of high water concentration through a semi-permeable membrane to a region of low water concentration.

Hypotonic soloutions are ones with a lower concentration of dissolved particles. Therefore a solution hypotonic to the cell's interior cytoplasim will cause water to enter by osomosis.

Wow, asking other people to do your homework is pretty bold. On the other hand if you're offering God's blessing...\nHere's something to get started with:\n1) answered by question #2\n3)think about how osmosis works\n5)Diabetes/Diabetic ketoacidosis (DKA) hopefull this will inform answers to the other questions\n8) What does polyuria mean? What is urine made out of? Where does it come from? \n11) If you are hypovolemic (dehydrated), what do you need? Furthermore, if the reason you are hypovolemic is beacuse your cells can't take up glucose, and therefore your blood sugar is high, and therefore you're peeing out all your water, what do you need to fix?

OPPS SORRY, I sent incomplete. Believe it or not, it is generally described as thus: The body wants to have 2/3 of the water inside the cells \n(intracellular fluid) and 1/3 of the water between the cells (extracellular) however a Teacher is probably looking for the technical name of: interstitial fluid

The Answer is quite simple. Isotonic solutions are defined as two or more solutions having the same solute concentrations.
