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.
Active transport requires the use of energy. it can either be primary active transport, where ATP is used to transport a substance into a cell, or secondary active transport (like a symporter) where the transporter uses another substance flowing down its concentration gradient into the cell to pull the target substance with it.
Passive transport involves transport that does not require energy. Ie. ion channels or simple diffusion.
active transport needs the cell to expand energy & passive doesn't.
Active transport requires energy for the organism to move things where as passive transport just relies on the net movement of things without the organism interfering.
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.
Active transport requires energy; passive transport does not.
Active transport requires energy while passive transport does not.

Active transport requires energy; passive transport does not.
Active transport requires energy; passive transport does not.
Active transport requires energy, passive transport does not.
Active transport requires energy for the organism to move things where as passive transport just relies on the net movement of things without the organism interfering.
passive doesn't neeed energy but active transport does
One is active and one is passive
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.
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.
Passive transport and active transport are transport of materials across membranes. Passive requires no energy, while active does.
Active transport requires energy; passive transport does not.
Active Transport is the passage of materials across the membrane through the expenditure of energy. Passive Transport is the passage of materials across the membrane without the expenditure of energy. Bulk Transport is the type of active transport. Diffusion and Osmosis are type of passive transport.
Active transport requires energy while passive transport does not.
