Osmotic pressure occurs when two solutions of different concentrations are separated by a semi-permeable membrane. Often the solute cannot move through the membrane, so there is pressure for the water to move from the less concentrated side to the more concentrated side, to dilute it.

What is The pressure exerted against the cell membrane and cell wall known as?
hydrostatic pressure or turgor (same thing)
What enables an organism to grow at high osmotic pressure?
cell wall
What is function of glucose in DNA extraction?
Maintaining the osmotic pressure to prevent the cell form bursting.
If the water concentration on the inside of the cell is lower than the concentration on the outside where will water move?
Osmotic pressure causes substances to flow from where they are more concentrated to where they are less concentrated, but also note that in the case of cells, some substances are pumped through cell membranes in an opposite direction than osmotic pressure would cause.
What is cytololysis?
The disolution or distruction of a cellCytolysis, or osmotic lysis, occurs when a cell bursts due to an osmotic imbalance that has caused excess water to move into the cell. It occurs in a hypotonic environment, where water diffuses into the cell and causes its volume to increase. If the volume of water exceeds the cell membrane's capacity then the cell will burst.The cell will only burst if the cell is an animal cell and it will only expand if it is a plant cell.
The pressure that is exerted on the inside of cell walls and that is caused by the movement of water into the cell?
Osmotic pressure across the cell wall, here called Turgor Pressure.
Does placing plant cells in a hypotonic solution causes the osmotic pressure to increase?
When a plant cell is placed in a hypotonic solution, the osmotic pressure tends to increase as the water in the cells moves to a place elevated in solute concentration. The osmotic pressure is the chief cause of support in numerous plants.
If you place a red blood cell in disstilled water what would happen to the cell And why?
The cell would swell and burst because of the osmotic pressure causes water to move into the cell.
When water leaves a plant cell the osmotic pressure will increase of decrease?
The osmotic pressure will decrease. The osmotic pressure is decreased because the water is leaving the cell.
What is The pressure exerted against the cell membrane and cell wall known as?
hydrostatic pressure or turgor (same thing)
An animal cell that is surrounded by fresh water will burst because the osmosis pressure causes?
An animal cell that is surrounded by fresh water will burst because the osmotic pressure causesAn animal cell that is surrounded by fresh water will burst because the osmosis pressure causes the cytoplasm is hypertonic where it will absorb water hence swells leading it to burst.
What enables an organism to grow at high osmotic pressure?
cell wall
What is the normal osmotic pressure in a human cell?
280 mm Hg. albumin, globulins, fibrinogens all contribute to osmotic pressure in the cells of the human body.
What is the name of the organelle that maintains osmotic pressure in a cell?
Osmotic balance maintained by several organells.Main organell is cell membrane.
What is the role of NaCl in Nutrient broth?
NaCl is generally added to the nutrient media for maintaining the Osmotic pressure. Maintaining osmotic pressure is important, because, increase or decrease in the osmotic pressure leads to cell burst or death due to the effect of osmosis. So, maintaining the osmotic pressure is done by adding correct amount of NaCl.
Starch and glycogen molecules are a means for a plant or animal cell to store what in order to keep the osmotic pressure in the cell constant?
In order to keep the osmotic pressure in the cell constant, starch and glycogen molecules are a means for a plant or animal cell to store glucose. Cells require sugar or glucose as a source of energy for many different functions.
Importance of osmotic pressure?
Secret. ^_^ Here is a simple experiment for Osmotic pressure in the blood :http://www.wisc-online.com/objects/ViewObject.aspx?ID=NUR4004 , My Bilogy teacher told me that Turgor pressure and Osmotic Pressure in plants are the same so if shes right, means osmostic pressure is the water that enters the cell and pushes against the cell wall which keeps the plant cell turgid.. Please make sure of what I said before spreading or learning.
