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 else can I help you with?
What is the diffusion of water through the cell membrane is called?
The diffusion of water through the cell membrane is called osmosis. Osmosis occurs when water molecules move 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.
What organelle involved the processes of osmosis an diffusion?
Osmosis and diffusion take place across the plasma membrane, the outer "wall" of the cell. It is considered to be an organelle because it carries out a variety of functions. The cell membrane or plasma membrane is made up of a double layes of phosphorous and lipid molecules, known as the 'phospholipid bilayer'.
Diffusion osmosis active transport all of these are methods by which a cell?
Diffusion, osmosis, and active transport are methods by which a cell can move molecules across its membrane. Diffusion is the passive movement of molecules from an area of high concentration to low concentration. Osmosis is the diffusion of water molecules across a selectively permeable membrane. Active transport requires energy to move molecules against their concentration gradient.
What types of transport mechanisms through the cell membrane are passive?
diffusion, facilitated diffusion, and osmosis
What process do water molecules cross the cell membrane?
Water molecules cross the cell membrane through a process called osmosis, which is driven by the concentration gradient of water inside and outside the cell. Aquaporin proteins on the cell membrane facilitate the movement of water molecules into and out of the cell.
What the diffusion of water across a cell's membrane?
The diffusion of water through a cell membrane is called osmosis.
Explain the differences among diffusion facilitated diffusion and osmosis?
osmosis is the movement of water across the plasma or cell membrane
Is a special type of diffusion that involves moving across a cell membrane?
osmosis is a special type of diffusion that involves water moving across a cell membrane hopefuly this helped :)
What Small droplets of liquid can pass through a cell membrane by the process of?
One method of movement across the membrane is by diffusion, which is related to osmosis.
Particles moving across a cell membrane without using energy?

Osmosis is the diffusion of?
Osmosis is the diffusion of water across the cell membrance
What two processes move large packets of molecules across the cell membrane?
osmosis and diffusion

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 controls diffusion and osmosis in and out of a cell?
Diffusion and osmosis in and out of a cell are primarily controlled by the concentration gradient of solutes. Diffusion is the movement of molecules from an area of high concentration to low concentration, while osmosis is the movement of water across a selectively permeable membrane to equalize solute concentrations. Additionally, the permeability of the cell membrane to different solutes and the presence of transport proteins can also influence the rate of diffusion and osmosis.
What are 2 ways that substances across the cell membrane without using energy?
simple diffusion, facilitated diffusion, and osmosis (water)
