What happens to a higher concentration of dissolved molecules on one side of a cell membrane during the process of diffusion?
the side of the cell membrane with the higher molecule concentration moves molecules to areas of lower concentration during diffusion until an equilibrium is reached between both sides of the membrane.
What is a membrane that only allows certain materials to pass through?
A membrane that permits the passage of only certain molecules is called a semi-permeable membrane. In its simplest form, this separation process is based on molecular size. Smaller molecules pass through and larger ones are retained. In most biochemical processes, a concentration gradient drives the movement of molecules through the membrane.
How does the cell membrane control the movement of materials into and out of the cell?
The cell membrane is partially permeable and it is designed in a way such that only particular objects can enter and leave; the process by which they enter and exit the cell is known as diffusion which occurs due to osmosis.
What does plsma membrane do?
The plasma membrane, also known as the cell membrane, allows only certain material to pass into and out of the cell.
Why is the plasma membrane selectively permeable?
The plasma membrane is selectively permeable because it needs to allow certain things in and certain things out.The plasma membrane is a selectively permeable membrane as it allows the entry and exit of some selected substances only.
What is diffusion and how does it relate to plasma membrane?
Diffusion is simply the movement of one molecule from an area of high concentration to low concentration. It is semi related to the plasma membrane because plasma membrane does allow diffusion, to an extent. Plasma membrane is semipermeable and only allows certain things to diffuse in or diffuse out.

What is osmosis diffusion?
(WATER CELLS ONLY)Water cells move from a higher concentration gradient (more water cells) to a lower concentration gradient (less water cells) through a partially permeable membrane (allows certain substances in and out) and goes with the concentration gradient (high -> low)
What is diffusion in biology?
Diffusion is the process that occurs when a certain concentrated volume of material moves to a less concentrated state. Facilitated diffusion is different and is done with the help of pumps actively transporting materials across the cell membrane to create the equilibrium on both sides of the membrane. ža specific type of passive transport žthe movement of particles from an area of high concentration to an area of low concentration ždissolved particles that are small or nonpolar can diffuse through the cell membrane ždiffusion is used to reach equilibrium –equilibrium: a condition in which the concentration of a substance is equal throughout a space
What is the purpose for diffusion and osmosis?
There is no real purpose. But they are both forms of particle movement across the concentration gradient (from high concentration). You could say that the purpose is to balance the amount of a certain particle. NATURE HATES HIGH CONCENTRATION OF PARTICLES IN ONE AREA! :)
What are the differences between grants and scholarships for school?
Grants are given to you for certain requirements that you have done. As a scholarship is something that you qualify for automatically and pays into your tuition. Scharlorships are given to you and you have to maintain a certain gpa. grants you dont have to
What is a membrane called when only certain things can cross a membrane?
a membrane that only allows certain things to cross is called "selectively permeable"
In osmosos how do molecules move?
Water molecules move with the help of membrane proteins called aquaporins, which regulate the movement of water in an out of the cell. Because of the dual nature of the membrane (hydrophobic and hydrophilic), water doesn't simply diffuse in an out, although a certain percentage can slip in between phospholipids.
What is the diffusion of water molecule through a selectively permeable membrane?
It's called osmosis. A selectively permeable membrane will only allow certain molecules to pass trough. To illustrate: If you have a high concentration of sugar molecules on one side of the membrane, no sugar on the other side, and the sugar molecules are too big to pass trough the membrane. If this is the case, then water molecules will diffuse over to the side of the membrane with a high sugar concentration. This happens because the molecules try to distribute themselves evenly in the solution. The water molecules move because the sugar molecules can't.

What only allows certain substances in and out of a cell?
The permeability of the cell membrane controls which substances may pass in or out of the cell.
