What are the 3 methods of passive transport?
The three methods of passive transport are simple diffusion, facilitated diffusion, and osmosis. Simple diffusion involves the movement of molecules across a membrane from an area of high concentration to low concentration. Facilitated diffusion uses carrier proteins to help larger or charged molecules move across the membrane. Osmosis specifically refers to the movement of water molecules across a selectively permeable membrane.
What two requirements distinguish osmosis from diffusion?
Osmosis involves the movement of water molecules across a semi-permeable membrane, while diffusion involves the movement of particles (e.g., ions, molecules) from an area of higher concentration to an area of lower concentration. The key requirements that distinguish osmosis from diffusion are the presence of a semi-permeable membrane and the movement of water molecules specifically in osmosis.
Three types of passive transport?
Simple diffusion: Small, non-polar molecules move across the cell membrane without the need for energy. Facilitated diffusion: Larger or polar molecules use carrier proteins to move across the cell membrane without energy expenditure. Osmosis: The movement of water molecules across a selectively permeable membrane from an area of low solute concentration to an area of high solute concentration.
What is the movement of molecules from greater to lower?
This movement is called diffusion, where molecules move from an area of higher concentration to an area of lower concentration in order to achieve equilibrium. The process is driven by the random motion of molecules and does not require energy input.
What are the particle involved in diffusion?
Diffusion is due to the Transitional movement of molecules or particles.
Types of passive transport involves the movement of water and solute molecules due to hydrostatic pressure?
Diffusion involves the movement of material from an area of high concentration to an area of low concentration.Osmosis is a type of diffusion that specifically involves the movement of water.Facilitated diffusion is also a type of diffusion that uses special transport proteins to transfer larger molecules, such as glucose, across cell membranes.Filtration involves the movement of water and solute molecules across the cell membrane due to hydrostatic pressure. This pressure is generated by the cardiovascular system as blood is pumped through the body's blood vessels.so therefore Filtration is the answer.
How are diffusion and filtration alike?
Both move down concentration gradient through a partially permeable membrane, and both do not require energy. Diffusion involves the movement of particles or solute from an area of high concentration to an area of low concentration. Osmosis is the movement of water from where it is in high concentration to where it is in low concentration.
Compare osmosis diffusion and filtration?
Osmosis is the movement of water molecules across a selectively permeable membrane from an area of lower solute concentration to an area of higher solute concentration. Diffusion is the movement of particles from an area of higher concentration to an area of lower concentration until equilibrium is reached. Filtration involves the movement of particles through a barrier, typically driven by a pressure gradient, with the goal of separating substances based on size.
Why the osmosis involves the movement of molecules via special transport protein?
facilitated diffusion
What types of passive transport involves the movement of water and solute molecules due to hydrostatic?
filtration

What is the difference between diffusion and omosis?
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. Osmosis is a type of diffusion that involves water molecules.
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.
What incudes diffusion osmosis and facitated diffusion?
Diffusion is the movement of particles from an area of high concentration to low concentration. Osmosis is the specific type of diffusion where water molecules move through a selectively permeable membrane. Facilitated diffusion involves the movement of specific molecules across a membrane with the help of transport proteins.
Diffusion is the movement of molecules from?
Diffusion is the movement of molecules from an area of high concentration to an area of low concentration.
Is osmosis the diffusion of small molecules?
Yes, osmosis is the diffusion of water molecules across a semi-permeable membrane. It is a specific type of diffusion that involves the movement of water from an area of higher concentration to an area of lower concentration.
Differentiate between osmosis and diffusion?
Osmosis is the movement of water molecules across a semipermeable membrane from an area of lower solute concentration to an area of higher solute concentration. Diffusion is the movement of molecules from an area of higher concentration to an area of lower concentration, without the need for a membrane. Osmosis specifically involves water molecules, whereas diffusion can occur with various types of molecules.
