If the diffusion is moving particles from higher to lower concentration, it uses no energy from the cell; this is passive diffusion. However, if it is active diffusion, the cell is pumping out specific molecules into a higher concentration, therefore using energy.

A cell moves particles from a region of lesser concentration to a region of greater concentration by what?
The process in which particles move from high to low concentration is called diffusion .
What are the process in which materials move through a cell membrane?
diffusion and osmosis
What type of transport supplies a cell with glucose?
thanks to: Bobama 08. question: what transport supplies a cell with glucose? answer: The passive transport supplies a cell with glucose. A passive transport is the diffusion of particles through the proteins. The particles move from an area of high concentration to an area of low concentration. The cell does not need to use any energy to make this happen. Whereas, an active transport is the movement of particles through proteins against the normal direction of diffusion. Particles are moved from an area of low concentration to an area of high concentration. The cell must use energy to make this happen. This energy comes from the molecule ATP, which stores energy in a form that cells can use. Therefore, the passive cell transport supplies a cell with glucose.
What is the process in which molecules move in and out of cell?
The movement of things through the cell would be called diffusion. If it is water we are talking about then it is called osmosis. diffusion and osmosis are examples of inactive transport. Active transport involves specific proteins in the cell that pull material in the cell though the cell membrane.
How are diffusion and the cell membrane related?
Diffusion is essential for cells to bring nutrients and releasing wastes WITHOUT spending energy. This is accomplished by the "urge" of a system to achieve equilibrium, which means that materials tend to flow from high concentration to low concentration area. For example, if a cell lacks amino acids, and therefore has a low concentration of it inside the cell compared to the outside, then by diffusion, the amino acids outside will flow in through the membrane until the concentrations of amino acids outside and inside the cell are the same. All these are done without spending energy from the cell. Note, however, that simple diffusion cannot transport larger particles or those insoluble in lipids; these materials have to be transported with facilitated diffusion, where a carrier on the membrane of the cell will help bring in the materials.Diffusion is when particles in a more concentrated area move to a less concentrated area, through a semi- permeable membrane. Without diffusion, the cells in your body will not be able to obtain the resources they need to survive, like water and proteins.
What statements tells how facilitated diffusion differ from simple diffusion?
Particles move through cell membranes w/out the use of energy by cells.
Is diffusion part of an active transport?
No, diffusion is where particles flow in order to be equal, whereas active transport uses ATP to move them through a cell membrane.
A cell moves particles from a region of lesser concentration to a region of greater concentration by what?
The process in which particles move from high to low concentration is called diffusion .
What substances would be moved across the cell membrane by diffusion?
Smaller particles are more likely to move by diffusion. Fat soluble substances are also more likely to move through diffusion also.
What are the types of particle transport how particles move into and out of the cell?
The types of particle transport mechanisms by which particles move into and out of the cell are diffusion, osmosis, and active transport.
Where will particles move when they are crowded?
The answer is called diffusion
How does sodium ion molecule move into the cell through cell membrane?
Through diffusion.
What is it called when particles travel from an area of high concentration to an aera of low concentration?
Through passive transport
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 are the process in which materials move through a cell membrane?
diffusion and osmosis
Which material move through the cell in diffusion?
All the imports and exports of cell moves through plasma membrane by diffusion. Which includes proteins, water, nutrients and the products of the cell. The material in excess amount in or out of the call moves in or out of the by diffusion.
How do proteins and polysaccharides that are too large to move onto a cell through diffusion or active transport move into the cell by?
Endocytosis.
