Amoeba have special vacuoles that fill up with water, then moves outside of the cell and bursts. The concentration of water outside the amoeba is higher than inside the cell, because the vacuole contains mineral salts. So the concentration of water inside the vacuole is low. Therefore water molecules move from outside of the cell into the vacuole due to osmosis. Then when the vacuole becomes full it goes outside of the cell and bursts. A new vacuole is then made.
What else can I help you with?
How does osmosis and diffusion work in amoeba?
Amoeba obtains oxygen via diffusion; it takes in water by osmosis, but I would think this is more of a problem, since Amoeba lives in a freshwater environment, and water is always entering by osmosis. Amoeba's problem is getting rid of that water, which it does by means of contractile vacuoles.
What would happen to fresh water amoeba if placed in salty water?
Freshwater amoeba placed in salty water would experience water leaving their cells through osmosis, leading to dehydration, shrinkage, and eventually cell death. The high salt concentration outside the amoeba would create a hypertonic environment, causing water to flow out of the cell to try to balance the concentration difference.
Is the movement of water in a hypertonic solution from a high concentration to a low concentration?
Yes, the movement of water in a hypertonic solution is from an area of high concentration to an area of low concentration.
What is a special form of diffusion where water moves from an area of high water concentration to an area of low water concentration?
This is not special at all, it is what happens normally. You can also think of it as water moving down a solute gradient (from low solute concentration to high solute concentration, till the concentrations are the same. The name for this process is osmosis.
The movement of water from an high concentration to an area of low concentration is called?
The movement of WATER from a high concentration area to a area of low concentration is called osmosis, but the the movement of MOLECULES from a high concentration area to an area of low concentration (like perfume when you spray from a high place) causes it to diffuse.

Why does water move into the amoeba living in fresh water?
When single cell freshwater organism is transferred in salt water it will shrink. For e.x. As in case of amoeba if fresh water amoeba is kept in salt water it contractile vacuole will disappear and this phenomena is called osmoregulation.

Freshwater amoeba placed in salty water would experience water leaving their cells through osmosis, leading to dehydration, shrinkage, and eventually cell death. The high salt concentration outside the amoeba would create a hypertonic environment, causing water to flow out of the cell to try to balance the concentration difference.
Is osmosis high to low or low to high concentration?
Osmosis is the movement of water from an area of high water concentration to an area of low water concentration through a semi-permeable membrane.
Do osmosis has a high or low concentration?
As per Definition of osmosis: "Osmosis is the passage of water from the region of high water concentration through a semi permeable membrane to a region of low water concentration". Thus, Osmosis do have an area of high and low concentration of water solutions.
What is the process of water from an area of low solute concentration to an high solute of high concentration?
Osmosis is the process of water moving from an area of low solute concentration to an area of high solute concentration.
The net movement of water across a membrane from the solution of lower concentration to one of higher concentration is called?
This is referred to as OSMOSIS. When you say "solution of lower concentration" this implies the solute concentration is low, thus water concentration is high. So, osmosis is movement of water from a high concentration of water, to a lower concentration of water, just to be clear.
Is the movement of water in a hypertonic solution from a high concentration to a low concentration?
Yes, the movement of water in a hypertonic solution is from an area of high concentration to an area of low concentration.
What is it called when water molecules move from a low concentration of a solutes to a high concentration of solutes?
Osmosis. A solution with a low concentration of solutes would have a higher concentration of water than a solution with a high concentration of solutes. So in this case, water is moving from a higher concentration of water to a lower concentration of water, which is osmosis.
What is it called when water molecules move from a low concentration of solutions to a high concentration of solutes?
Osmosis. A solution with a low concentration of solutes would have a higher concentration of water than a solution with a high concentration of solutes. So in this case, water is moving from a higher concentration of water to a lower concentration of water, which is osmosis.
What is it called when water molecules move from a low concentration of solutes to high concentration solutes?
Osmosis. A solution with a low concentration of solutes would have a higher concentration of water than a solution with a high concentration of solutes. So in this case, water is moving from a higher concentration of water to a lower concentration of water, which is osmosis.
What is the movement of water through a membrane from areas of high concentration to areas of low concentration?
Osmosis is the movement of water through a selectively permeable membrane from an area of high concentration of water to an area of low concentration of water.
