According to the Oxford English Dictionary, osmosis is defined as "a process by which molecules of a solvent tend to pass through a semipermeable membrane from a less concentrated solution into a more concentrated one" (OED 2013). The greater mass present in the higher concentrated solution of the solvent causes the water molecule to pass through the sempermeable membrane until the water concentration of water with concentrated solution are balanced on both sides.
The direction of water movement during osmosis is controlled by the concentration gradient of solutes across the semipermeable membrane. Water will move from an area of lower solute concentration to an area of higher solute concentration to equalize the concentration on both sides of the membrane.

What solution is the control of the cell during osmosis?
The cell controls osmosis by regulating the movement of water through the cell membrane. This is done by osmoregulation, which involves adjusting the concentration of solutes inside the cell to maintain a balance with the external environment. In this way, the cell can prevent excessive water loss or gain and maintain proper cell function.
Why do you need to remove the skin of a potato during osmosis?
Removing the skin of a potato during osmosis allows the movement of water and solutes to occur more easily. The skin acts as a barrier that can impede the flow of water and nutrients in and out of the potato cells. By removing the skin, osmosis can happen more efficiently.
What is an example of osmosis in humans?
An example of osmosis in humans is the movement of water from the bloodstream into the cells lining the small intestine during digestion. This helps to maintain the balance of water and nutrients needed for proper absorption.
Is the movement of water molecules during osmosis due to active transport?
No, the movement of water molecules during osmosis is passive and does not require energy input from the cell. It is driven by the concentration gradient of solutes across a selectively permeable membrane. Active transport, on the other hand, requires energy to move molecules against their concentration gradient.
Why does it get damp in the potato osmosis?
During the potato osmosis experiment, the water molecules move from the area of higher concentration (outside the potato cells) to the area of lower concentration (inside the potato cells). This movement of water causes the potato to absorb water and become damp.
Osmosis always involves the movement of what?
Osmosis always involves the movement of water. During osmosis water will move in and out of the cell or membrane.
How do you predict the direction of the water flow during osmosis?
Water will flow from an area of lower solute concentration to an area of higher solute concentration during osmosis. This movement equalizes the concentration of solutes on both sides of the membrane.
Which body system controls the movement of the ribs in breathing?
The nervous system controls the movement of the ribs during breathing. The movement is performed by the musculoskeletal system.
What molecules move across during osmosis?
Water molecules are the primary molecules that move across during osmosis. Osmosis is the movement of water molecules from an area of higher concentration to an area of lower concentration across a selectively permeable membrane.
What molecule moves across the membrane During osmosis?
Water molecules move across the membrane during osmosis. Osmosis is the movement of water molecules from an area of lower solute concentration to an area of higher solute concentration across a semi-permeable membrane.
What solution is the control of the cell during osmosis?
The cell controls osmosis by regulating the movement of water through the cell membrane. This is done by osmoregulation, which involves adjusting the concentration of solutes inside the cell to maintain a balance with the external environment. In this way, the cell can prevent excessive water loss or gain and maintain proper cell function.
When does movement of a substance across a cell membrane using chemical energy occur?
During osmosis and uptake of minerals.
Which type of molecules cross the membrane in osmosis?
Water molecules cross the membrane during osmosis. Osmosis is the movement of water across a semi-permeable membrane from an area of lower solute concentration to an area of higher solute concentration.
What material diffuses across the cell membrane during osmosis?
Water molecules diffuse across the cell membrane during osmosis. Osmosis is the movement of water from an area of high concentration to an area of low concentration, across a semi-permeable membrane. This process helps maintain the balance of water inside and outside the cell.
Why do you need to remove the skin of a potato during osmosis?
Removing the skin of a potato during osmosis allows the movement of water and solutes to occur more easily. The skin acts as a barrier that can impede the flow of water and nutrients in and out of the potato cells. By removing the skin, osmosis can happen more efficiently.
