What else can I help you with?
Is it true if the process by which water moves across a selectively permeable membrane is called diffusion?
Diffusion is a physical process. When it is performed through a selectively permeable membrane, it is called osmosis. Thus osmosis is an appropriate word for movement of water molecules through a selectively permeable membrane and not diffusion.
What term refers to diffusion of water molecules through a selectively preamble membrane?
Osmosis is the diffusion of water molecules through a semi-permeable membrane to equalise osmotic pressure.
How does oxygen cross a selectively permeable membrane?
diffusion
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 includes diffusion osmosis and facilitated diffusion?
These processes involve the movement of molecules across a semi-permeable membrane. Diffusion is the passive movement of molecules from an area of high concentration to an area of low concentration. Osmosis is the diffusion of water molecules across a selectively permeable membrane. Facilitated diffusion is the passive transport of molecules across a membrane with the help of specific proteins.
What involves the movement of solutes across a selectively permeable membrane by the process of difussion?
Osmosis involves the movement of solutes across a selectively permeable membrane by the process of diffusion. In osmosis, water molecules move across the membrane from an area of low solute concentration to an area of high solute concentration in order to equalize the concentration on both sides of the membrane.
How is diffusion different from osmosis?
Diffusion is the movement of molecules from an area of high concentration to an area of low concentration, while osmosis specifically refers to the movement of water molecules across a selectively permeable membrane.
What is definition of selectively permeable?
The selectively permeable phospholipid bilayer (a.k.a plasma membrane) is 'selectively permeable' because it selects which molecules it allows to permeate (pass through).
What is a selectlively permeable membrane?
The cell membrane is selectively permeable, allowing some molecules to pass through by osmosis
What process - movement of water across a selectively permeable membrane from an area of high water concentration to an area of low concentration?
Osmosis is the process by which water moves across a selectively permeable membrane.
How can dialysis tubing be used to model a selectively permeable membrane?
Dialysis tubing can model a selectively permeable membrane by allowing certain small molecules and ions to pass through while restricting larger molecules. When filled with a solution and submerged in another solution, the tubing will permit the diffusion of substances like water, glucose, and ions based on concentration gradients. This setup effectively demonstrates principles of osmosis and diffusion, illustrating how cells selectively allow materials in and out. By observing changes in mass or concentration, one can visualize the behavior of a selectively permeable membrane in biological systems.
What are the differences between diffusion facilitated diffusion and osmosis?
Diffusion is the movement of molecules from an area of high concentration to low concentration. Facilitated diffusion involves the use of transport proteins to move specific molecules across the cell membrane. Osmosis specifically refers to the movement of water molecules across a selectively permeable membrane.
