What else can I help you with?
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.
What is the diffusion of water across a semipermeable memberane?
Diffusion of water across a semipermeable membrane is a type of simple diffusion given the special name of osmosis.
A form of passive transport that involves membrane proteins to aid in the movement of substances?
Facilitated diffusion is a form of passive transport that involves membrane proteins to aid in the movement of substances across a cell membrane. The membrane proteins act as channels or carriers to facilitate the passage of specific molecules that cannot freely diffuse across the lipid bilayer. This process does not require energy input from the cell.
Does osmosis or facilitated diffusion require the presence of membrane channels?
Facilitated diffusion requires the presence of membrane channels or transporters to move molecules across the membrane. Osmosis, on the other hand, does not require membrane channels as it involves the passive movement of water molecules through the lipid bilayer of the membrane.
What are the two types of possive transport?
The two types of passive transport are simple diffusion and facilitated diffusion. Simple diffusion involves the movement of molecules across a cell membrane without the need for a specific protein. Facilitated diffusion, on the other hand, requires the assistance of specific transport proteins to move molecules across the membrane.
What is the diffusion of water across the semipermeable?
Diffusion of water across a semipermeable membrane is a type of simple diffusion given the special name of osmosis.

Diffusion of water across a semipermeable membrane is a type of simple diffusion given the special name of osmosis.
What is the difference between facilitated diffusion and simple diffusion in terms of the mechanisms by which molecules move across a cell membrane?
Facilitated diffusion involves the movement of molecules across a cell membrane with the help of specific proteins, while simple diffusion does not require any proteins and relies on the molecules moving freely through the membrane.
How is osmosis a special kind of diffusion?
Osmosis is a special kind of diffusion because it specifically involves the movement of water molecules across a selectively permeable membrane. In osmosis, water moves from an area of higher concentration to an area of lower concentration to achieve equilibrium. This process is important for maintaining the balance of fluids in cells and tissues.

Facilitated diffusion requires the presence of membrane channels or transporters to move molecules across the membrane. Osmosis, on the other hand, does not require membrane channels as it involves the passive movement of water molecules through the lipid bilayer of the membrane.
A special form of diffusion that applies only to water?
Osmosis is the special form of diffusion that applies only to water. It is the movement of water molecules from an area of high concentration to an area of low concentration across a semipermeable membrane.
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 are the two types of possive transport?
The two types of passive transport are simple diffusion and facilitated diffusion. Simple diffusion involves the movement of molecules across a cell membrane without the need for a specific protein. Facilitated diffusion, on the other hand, requires the assistance of specific transport proteins to move molecules across the membrane.
What are the three forms of passive transport and how do they differ in their mechanisms of movement across the cell membrane?
The three forms of passive transport are diffusion, facilitated diffusion, and osmosis. Diffusion involves the movement of molecules from an area of high concentration to an area of low concentration. Facilitated diffusion uses protein channels to help molecules move across the membrane. Osmosis is the movement of water molecules across a selectively permeable membrane.
Which involves a membrane - diffusion or osmosis?
Osmosis involves a membrane. It is the movement of water molecules across a selectively permeable membrane from an area of low solute concentration to an area of high solute concentration. Diffusion, on the other hand, is the movement of particles from an area of high concentration to an area of low concentration, and it can occur with or without a membrane.
