Diffusion is defined as a movement of molecules?
Is Diffusion the movement of molecules from a greater to a lesser concentration.
What process - movement of water across a selectively permeable membrane from an area of high water concentration to an area of low concentration?
Osmosis is the process by which water moves across a selectively permeable membrane.
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.
The process where a nonpolar molecule can just passively get across a membrane is called?
facilitated diffusion
What is the passive transportation of substances across the cell membrane called?
When a substance moves from an area of low concentration to an area of high concentration while using energy the process is called active transport.

What process - movement of water across a selectively permeable membrane from an area of high water concentration to an area of low concentration?
Osmosis is the process by which water moves across a selectively permeable membrane.
The process that occurs when a physical pressure pushes materials through a barrier is called?
Osmosis is the movement of water across the membrane, while diffusion is the movement of solids across a membrane Diffusion ordinarily does not require a membrane.The movement of particles of a substance by their own kinetic energy from their higher concentration to lower concentration is called diffusion.
What motion of particles across a membrane requires energy?
Movement across a membrane that does require energy is called active transport.
What is it called when particles travel from an area of high concentration to an aera of low concentration?
Through passive transport

The movement of a substance across a concentration difference is called?
diffusion
What is simple diffusion of water through a membrane called?
Osmosis is the term for the diffusion of solute through a membrane from a place of higher concentration to a place of lower concentration. The process of osmosis will continue until the concentration is equal on both sides of the membrane.
What is net movement of particles from an area of higher concentrations to an area of low concentrations called?
Diffusion is the passive movements of particles from an area of higher concentration to an area of lower concentration. Osmosis is the movement of water molecules across a partially permeable membrane from a region of higher water concentration to a region of lower concentration.
The process where a nonpolar molecule can just passively get across a membrane is called?
facilitated diffusion
What is the passive transportation of substances across the cell membrane called?
When a substance moves from an area of low concentration to an area of high concentration while using energy the process is called active transport.
What is the diffusion of water across a selectively premeable membrane called?
It is osmosis .
