The primary drivinf force for diffusion is a concentration gradient. There has to be an abundance of molecules at one region and a scarcity of molecules at another. This differential distribution of molecules where one region has more than the other is called a concentration gradient. In the presence of this gradient, diffusion occurs without the expenditure of energy. In cells, diffusion can occur through the cell membrane. Water molecules move into or out of the cell depending on where there are more water molecules. If there is more water outside the cell, water molecules move in and vice versa.

When water diffuse across a membrane how does it diffuse?
Diffuses when water is needed inside of the cell. It usually happens by a hyper-tonic or hypo-tonic solution. Wherever there is a high and low.. water diffuses. Water usually diffuses high to low. Water or any substance that has the ability to diffuse always diffuses from a high concentration to a low concentration. Through a cell memrane, it's the same thing. When we drink water, we gulp down a whole mouthfull. When it's time for it to diffuse, it goes into different cells. We drink in a high c. and the water goes in the cells in low concentration. Same thing when the water wants to come out. It goes to another place that needs it.
What changes would take place in the chlamydomonas cell if it were transfered to sea water?
As there is a higher concentration of salt in the sea water, salt will diffuse into the cell and this will cause the cell to shrink.
What are the conditions needed for growth seedling?
well you need to water it and make sure it is in a warm place or location.
When the concentration of free water molecules is higher outside a cell than inside the cell water will diffuse?
In this situation there will be endo-osmosis. The water molecules will diffuse from outside to inside cell.
What are the main substances that diffuse out of leaves?
water and oxygen
What are conditions necessary to cause water to diffuse out of a cell?
If the concentration of water inside the cell is higher, water will leave the cell. This would happen if a cell is placed in a hypertonic solution.

What is the effect of salt on plants?
Salts will cause water to diffuse out of plant vacuoles, leading their cells to become flaccid. Thus, the plant will wilt.
