What is the process of moving particles across the plasma membrane of a cell by diffusion?
Known as diffusion, in which a higher concentration of a substance passes across a semi permeable membrane to a lower concentration until equilibrium is reached. The other side of the coin is osmosis, in which fluid is drawn towards a regeon of higher concentration of a substance until equilibrium is reached.
eg! A teabag. The staining of the water around the teabag is diffusion, and the wetting ( saturation ) Of the leaves is osmosis. Both across the semi permeable membrane of the bag ( Cell ).
What else can I help you with?
The process where a nonpolar molecule can just passively get across a membrane is called?
facilitated diffusion
Is it from high concentration to low that particles move across a membrane move?
Yes. It is called Osmosis. Particles move across the membrane in order to balance the concentration of particles on both sides of the membrane. Since the membrane tends to block the larger particles, its the smaller molecules that move, so what happens across membranes is that the motion (of say water) is from low concentration toward higher - but the result is to even the concentration on both sides of the membrane, Pure diffusion is always from higher concentration to lower.
What is the process that utilizes a carrier to move materials across the plasma membrane in the direction of the concentration gradient that does not use ATP?
Active Transport
Is diffusion of molecules across the cell membrane the most complex type of active?
Diffusion of molecules across the cell membrane is actually a passive process, not active. Active transport, which requires energy in the form of ATP, is a more complex process as it moves molecules against their concentration gradient.
What moves particles like oxygen into cells?
Particles like oxygen are moved into cells through the process of diffusion. This is a passive process where particles move from an area of high concentration to an area of low concentration, crossing the cell membrane. Additionally, specialized proteins like transporters and channels can facilitate the movement of specific particles into cells.
What motion of particles across a membrane requires energy?
Movement across a membrane that does require energy is called active transport.
How is equilibrium related to diffusion and osmosis?
Equilibrium in diffusion and osmosis is reached when there is a balanced distribution of particles or solutes across a membrane, resulting in no net movement of particles. In diffusion, equilibrium is reached when there is an equal concentration of particles on both sides of the membrane. In osmosis, equilibrium is reached when the water concentration is the same on both sides of the membrane.

What is the process that utilizes a carrier to move marerials across the plasma membrane in the direction of the concentration?
Diffusion is what carries materials across the plasma membrane. The diffusion cannot be moved across water.
Is it from high concentration to low that particles move across a membrane move?

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.
Diffusion of solvent particles across a semipermeable membrane?
Solvent particles will move from an area of high concentration to low concentration across a semipermeable membrane until equilibrium is reached. This process is known as osmosis and is driven by the natural tendency of molecules to move from areas of high to low concentration to equalize the concentration gradient.
