Osmosis is an example of movement of particles from an area without the need of additional energy. If a state is not in equilibrium particles can move from one area to another without additional energy.

Does passive transport take place without the use of energy?
Yes, passive transport takes place without the use of energy (ATP). This transport is made possible because the movement that occurs due to concentration or pressure differences. These passive processes are called diffusion and filtration. Diffusion (simple and faciliated diffusion and osmosis) occurs because of a concentration gradient and filtration occurs because of differences in pressure.
Do cells gain and then use energy through facilitated diffusion?
Cells do not gain (or use) energy through facilitated diffusion.
Does the facialited diffusion require the cell to use energy?
No, it does not require energy use from the cell.
How are diffusion and active transport different?
There are two types of diffusion. Facilitated and non facilitated. Diffusion occurs when there is a concentration gradient. That is, when an area has more concentration than the other area. Diffusion is used to transfer particles from one place to another. Active transport is used to transfer particles, usually occurring against a concentration gradient. Active transport requires energy to occur however, diffusion does not. There are two types of diffusion. Facilitated and non facilitated. Diffusion occurs when there is a concentration gradient. That is, when an area has more concentration than the other area. Diffusion is used to transfer particles from one place to another. Active transport is used to transfer particles when there is no concentration gradient. Active transport requires energy to occur however, diffusion does not.
Does a cell use energy when molecules diffuse in or out of the cell down the concentration gradient?
Diffusion is passive transport - it means that the cell doesn't use any energy transporting the materials. However, if there is more of a substance inside a cell than outside a cell (like nutrients), and the cell needs to get the nutrients in, diffusion will not owrk. The cell uses energy to do active transport and get the particles in.
Movement of water molecules without the use of energy?
Diffusion
What statements tells how facilitated diffusion differ from simple diffusion?
Particles move through cell membranes w/out the use of energy by cells.
What structures allow small particles to cross the cell membrane?
Small particles can cross the cell membrane through simple diffusion, facilitated diffusion, or active transport. In simple diffusion, particles move from an area of high concentration to low concentration without the need for energy. Facilitated diffusion involves the use of protein channels or carriers to aid in the movement of particles. Active transport requires energy and transport proteins to move particles against their concentration gradient.
How is diffusion SIMILAR to osmosis?
Neither of them require energy. that is the major difference.
What is it called when large particles need to use energy to pass through cell membranes?
Active Diffusion
What is the movement called when a cell does not use energy to move particles across the cell's membrane?
It is called passive diffusion.
What is the movement called when a call does not use energy to move particles across the cells membrane?
It is called passive diffusion.
Is endocytosis an example of diffusion?
Endocytosis is NOT an example of diffusion. It is an example of active transport whereas diffusion is a type of passive transport. The difference lies in the fact that diffusion does not require energy to take place, and endocytosis does.
Why do cells use the process of diffusion?
Diffusion is essential for cells to bring nutrients and releasing wastes without spending energy.
What is the process in which particles in gas or liquid moves from higher to lower concentration?
Particles in a gas or liquid moving from a region of higher concentration to a region of lower concentration represents passive transport. This does not use energy.
