Active transport is the movement of molecules across a membrane requiring energy to be expanded by the cell.
ACTIVE TRANSPORT REQUIRES ENERGY.
Passive transport is diffusion across a membrane requiring only random motion of molecules with no energy expanded by the cell. Osmosis is an example of this.
PASSIVE TRANSPORT REQUIRES NO ENERGY.

Active transport requires energy often, in a cell, in the form of ATP (adenine triphosphate), like a sodium-potassium channel in a cell.
Passive transport happens without the use of energy. An example of this is osmosis.
Active transport is the movement of solutes against concentration gradient or electrical gradient. The solutes pass from a low solute concentration to a higher solute concentration, therefore it is also known as "uphill transport" whereas, Passive Transport is the movement of solutes towards the concentration gradient or electrical gradient. The solutes pass from a high solute concentration to a low solute concentration, therefore it is also known as "downhill transport".
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.

The difference between active transport and passive transport is?
Active transport requires energy; passive transport does not.
What id the difference between active and passive transport?
Active transport requires ATP and passive transport does not. Active transport goes against the concentration gradient and passive transport goes with the concentration gradient and includes osmosis, diffusion and facilitated diffusion.
What is the defference between active transpors and passive transport?
The difference between active and passive transport, is that, active transport, requires energy input from the cell, in order to occur, unlike passive, which occurs, without any energy input.
How does active and passive transport help maintain homeostasis?
They transport fluid/water/materials across the cell memebtane
What is the main difference between active trasport and passive transport?
Active transport requires energy (ATP, GTP, etc) to work against the electrochemical gradient. Passive transport works with the electrochemical gradient and does not require energy. (Think diffusion)
What is differs between active transport and passive transport?
Active transport requires energy; passive transport does not.
What is the dif frence between active and passive transport?
Active transport requires energy, passive transport does not.
What energy is required for passive transport?
By definition, passive transport on a cellular level requires no energy other than some sort of gradient, whether of the molecule in question, or another whose movement across the membrane can be linked to the one of interest.
What is difference between active transport and passive 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
What is the differnce between active and passive transport?
passive doesn't neeed energy but active transport does
What is the purpose of a cell transport?
Cell transport is movement of materials across cell membranes. Cell transport includes passive and active transport. Passive transport does not require energy whereas active transport requires energy to proceed. Passive transport proceeds through diffusion, facilitated diffusion and osmosis.
What is the difference between passive and active transport across the plasma membrane?
Active transport is ATP dependent, whereas passive transport uses only the kinetic energy of the particles for movement across the plasma membrane- mastering A and P homework-
