How does osmosis and diffusion work across a cell membrane?
During osmosis, water molecules move across a cell membrane from an area of low solute concentration to an area of high solute concentration in order to balance the concentration of solutes on both sides of the membrane. Diffusion involves the movement of molecules from an area of high concentration to an area of low concentration across the cell membrane until equilibrium is reached. Both processes are passive and do not require energy input from the cell.
What does osmosis involve the movement of?
Osmosis involves the movement of water across a selectively permeable membrane from an area of higher water concentration to an area of lower water concentration, in order to equalize the concentration of solutes on both sides of the membrane.
The movement of water across a membrane is termed?
it is called osmosis and it is the net movement of water particles across a semi-permable membrane against the concentration gradient!
Which type of transport is the coupled passage of two materials across a membrane?
Symport is the type of transport that involves the coupled passage of two materials across a membrane in the same direction. It relies on a concentration gradient to move both substances across the membrane simultaneously.
What is transported across a membrane during osmosis?
During osmosis, water molecules are transported across a membrane from an area of higher concentration to an area of lower concentration.
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.
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.

The movement of water across a membrane is trem?
The movement of water across a membrane is termed osmosis. This process involves the movement of water molecules from an area of high concentration to an area of low concentration through a selectively permeable membrane, such as a cell membrane. Osmosis plays a crucial role in maintaining the balance of water and solutes within living organisms.
How do diffusion osmosis facilitated diffusion and active transport diffusion differ?
Diffusion is the movement of molecules from an area of greater concentration to an area of lesser concentration. e.g. Exchange of gases in the lungs or body tissues. Osmosis is the diffusion of water through a semi-permeable membrane from an area of low solute to an area of high solute concentration. Faciliated diffusion is the passive transport of molecules down a concentration gradient. It is simply diffusion that involves a protein to make diffusion happen more easily across a cell membrane. Active transport is the moving of substances across the cell membrane using the cell's energy. Molecules are moved against a concentration gradient, i.e they move from an area of lesser concentration to an area of greater concentration. Tlhis is done by a carrier molecules which gets its energy from ATP.
Which type of transport is the coupled passage of two materials across a membrane?
Symport is the type of transport that involves the coupled passage of two materials across a membrane in the same direction. It relies on a concentration gradient to move both substances across the membrane simultaneously.
Is osmosis with or against concentration gradient?
Osmosis is with the concentration gradient, meaning that it involves the movement of water molecules from an area of low solute concentration to an area of high solute concentration across a semi-permeable membrane.
There is a greater concentration of na plus and there is a greater concentration of k plus in the cell?
There is a greater concentration of Na plus outside and there is a greater concentration of K plus inside the cell. When the stimulus is delivered, the permeability of the membrane is changed, and Na plus diffuses into the cell, initiating the depolarization of the membrane.
Does osmosis use energy?
Yes, osmosis is a passive process that does not require energy input. It involves the movement of water molecules across a semipermeable membrane from an area of high water concentration to an area of low water concentration.
What do osmosis involves?
Osmosis involves the movement of water across a semi-permeable membrane from an area of lower solute concentration to an area of higher solute concentration, in order to equalize the concentration on both sides of the membrane. This process helps maintain the balance of water and solutes inside and outside of cells.
