Water molecules move with the help of membrane proteins called aquaporins, which regulate the movement of water in an out of the cell. Because of the dual nature of the membrane (hydrophobic and hydrophilic), water doesn't simply diffuse in an out, although a certain percentage can slip in between phospholipids.

∙ 14y agoThe water moves down the concentration gradient, from an area of high water concentration (i.e. less negative water potential) to an area of low water concentration (i.e an area of more negative water potential).

∙ 12y agoWater molecules are small enough to move freely across the plasma membrane without the use of cellular energy. In osmosis, water molecules move across the cell membrane from where they are in higher concentration to where they are in lower concentration. The concentration difference between the inside and the outside of the cell determines the direction of osmosis.

∙ 14y agoSome water just "leaks" through the membrane. But most cells have Aquaporins in their membrane to allow the water to pass through more rapidly.

What molecules move during osmosis?
water molecules move during osmosis
Why do dye molecules move?
the dye must move from the energy that the molecules provide
What molecules move across during osmosis?
The only molecules that move during osmosis are water (H2O) molecules.
Do molecules move more and move apart as temp increases?
As temperature increases, kinetic energy of the molecules increases also, making the molecules move faster and move apart if they are able, as in fluids and gases.
What state of matter has molecules that are vibrating?
It is the solid. The molecules in solid dont move much but they do move, just a bit.
How do you think molecules move in hot and in cold air?
In hot areas the molecules move quickly and in cold areas the molecules move slower.
How do you think the molecules move in hot and cold air?
In hot areas the molecules move quickly and in cold areas the molecules move slower.
What molecules move during osmosis?
water molecules move during osmosis
How does warm air molecules move?
The molecules in warm air move faster
What motion do molecules move when in cold water?
does molecules move in cold water
Why do dye molecules move?
the dye must move from the energy that the molecules provide
What molecules move across during osmosis?
The only molecules that move during osmosis are water (H2O) molecules.
What is statements about ice melting?
Water molecules move from their fixed positions
Do molecules tend to move into area where there are more molecules?
Molecules tend to move into areas where there are less molecules. This is called diffusion and can happen with or without energy.
Do molecules move more and move apart as temp increases?
As temperature increases, kinetic energy of the molecules increases also, making the molecules move faster and move apart if they are able, as in fluids and gases.
Do molecules move to areas where there are more molecules?
Yes.
When energy is converted to molecules and they move faster does temperature increase or decrease?
As molecules move faster, they cause friction, which increases the temperature of the molecules.
