How do water molecules move through the cell membrane during omosis?
With a specific channel protein called aquaporins.
What is osomsis and difusion?
Osmosis is the tendency of a solvent to travel across a semipermeable membrane (Semipermeable membrane- a membrane that allows some molecules to pass through but does not allow other molecules to pass through) into areas of higher solute concentration. Diffusion is the random motion of molecules from an area of high concentration to an area of low concentration.
Which term refers to the diffusion of water molecules through a slestively permaeable membrane?
The movement of water through a selectively permeable membrane is called diffusion. Water will always diffuse down a concentration gradient, from high solute concentration to low solute concentration.
What does osmosis do?
The random movement of water molecules through a partially permeable membrane from a higher concentration to a lower concentration.
What term describes the diffusion of the water through a semipermeable membrane down a concentration gradient?
Osmosis is the diffusion of water molecules down a concentration gradient through a semi-permeable membrane
What is The process by which small molecules pass through a membrane by moving from an area of high concentration to an area of low concentration is?
diffusion.
When molecules move from high concentration to low concentration this is called?
diffusion unless it is water molecules moving through a selectively permeable membrane in which case it is osmosis
What happens to a higher concentration of dissolved molecules on one side of a cell membrane during the process of diffusion?
the side of the cell membrane with the higher molecule concentration moves molecules to areas of lower concentration during diffusion until an equilibrium is reached between both sides of the membrane.
When molecules such as oxygen are moved into Cells along their concentration gradient directly through the Cell membrane - this is called?
Trans-membrane diffusion.
Which process would describe the movement of sugar molecules through a membrane from a region of higher concentration of a region of lower concentration?
Diffusion
How is osmosis related to water?
Osmosis is when water molecules pass through a membrane. For example, if there is more salt outside a cell then inside it, the process of osmosis transports water molecules outside the cell to equalize the concentration of salt. WordNet's definition: diffusion of molecules through a semipermeable membrane from a place of higher concentration to a place of lower concentration until the concentration on both sides is equal
How do cells control osimsis?
osmossis is the movement of water molecules through a state of high concentration to a state of low concentration through a semi-permeable membrane
