Diffusion is the form of passive transport that moves particles away from areas with more particles into areas with fewer particles.

What is the difference between passive and active transport across the cell membrane?
Wouldn't it be that active transport requires enegry and passive doesn't? Passive transport occurs when the concentration of something on one side of membrane is different from the concentration on the other side. It occurs when that substance can pass through the membrane, and always in the direction of more -> less. No energy is required to make the substance move; in fact, this movement generates energy. This is like rolling a rock down a hill--it just does it on its own. Active transport occurs in the opposite direction, from less -> more. It requires energy for transport. This is like rolling a rock up a hill--you have to push it the entire way! Both involve the transport of a substance across a membrane, and the change in concentrations on different sides of a membrane. Both are also important to the proper functioning of a cell. Active transport requires energy, but passive transport requires none. Active transport requires a special protein to make the transport occur, but passive transport requires none.
What are the different types of passive transport?
1. facilitative diffusion-transport proteins provide a pathway for certain molecules to pass 2. osmosis-the passive transport of water across a selectively permeable membrane 3. diffusion- the net movement of the particles of a substance from where they are more concentrated to where they are less concentrated. (out of a sophomore Biology book)... hope this helps <3
What is disfussion?
Process by which molecules tend to move from an area where they are more concentrated to an area where they are less concentrated.
The movement of the water from an area with lots of water into an area with less water?
Well, the movement of water is called osmosis. movement from high concentration to low concentration is called active transport.
Passive transport requires no what?
Passive transport occurs when substances cross the plasma membrane without any input of energy from the cell. No energy is needed because the substances are moving from an area where they have a higher concentration to an area where they have a lower concentration. Concentration refers to the number of particles of a substance per unit of volume. The more particles of a substance in a given volume, the higher the concentration. A substance always moves from an area where it is more concentrated to an area where it is less concentrated. It's a little like a ball rolling down a hill. It goes by itself without any input of extra energy.
What is passive membran transport?
The diffusion of substances across a membrane is called passive transport. Molecules move from where the substance is more concentrated to where it is less concentrated.
What is active trasportation?
active transportation is the movement of molecules from a less crowded area to a more crowded area. passive transportation is the movement of molecules from a more crowded area to a less crowned area.
What is the transport mechanism where a passive process pulls water from an area where there is more water to an area where there is less water?
osmosis

Is osmosis active or passive transport?
It is passive transport because the water flows from a more highly concentrated solution to a less concentrated solution.

What best describes passive transport?
it moves materials from areas of high concentration to areas of low concentrationit moves materials of high concentration to areas of low concentration
What is the different between passive and active transport?
One difference is energy consumption. Active transport requires the cell to expend energy, while passive transport does not. Active transport is movement from a lower concentration to a higher concentration and passive transport is movement from a higher concentration to a lower concentration. Active transport is the movement of molecules across a membrane requiring energy to be expended by the cell. Passive transport is diffusion across a membrane requiring only random motion of molecules with no energy expanded by the cell. Active transport requires ATP to transport materials. Passive transport does not require ATP input to transport materials. Ex: diffusion
When stuff diffuses why does it always go to a less concentrated area?
When matter diffuses through a cell it moves from an area of higher concentration to an area of lower concentration. This process is called passive transport, which requires no energy. Opposite to that, active transport requires energy, or ATP, because it is moving things from an area of lower concentration to higher.
Does active transport move from higher to lower concentration?
Active Transport- When molecules move from an area of lower concentration to an area of higher concentrationPassive Transport- When molecules move from an area of higher concentration ot an area of higher concentration (also called diffusion)
What particles are able to pass freely through a cell membrane?
This is unique to each cell. Some particles are small enough to diffuse freely in most cells. Other particles require varying types of transport mechanisms to cross the cell membrane. If it is a substance the cell either needs to take in or get rid of, there are proteins and other mechanisms to accomplish this. There are even actions of the cell in order to export or import substances.
