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.

Does the process of transport, whether passive or active, require energy?
Yes, the process of transport, whether passive or active, requires energy.
What are passive and active transport?
Passive transport is the movement of molecules across a cell membrane without requiring energy, such as diffusion and osmosis. Active transport, on the other hand, requires energy to move molecules against their concentration gradient, typically using protein pumps or transporters.
What id the difference between active and passive transport?
Active transport requires energy to move molecules against their concentration gradient while passive transport does not require energy and moves molecules from high to low concentration. Active transport is selective and can transport specific molecules, while passive transport is nonselective and moves molecules based on their concentration gradient.
How are active transport and passive transport different from each other?
Active transport requires energy input to move substances across a membrane against their concentration gradient, while passive transport does not require energy as it moves substances along their concentration gradient. Active transport is selective and requires specific transport proteins, while passive transport occurs through simple diffusion or facilitated diffusion.
What is the difference between active and passive cellular transport?
Active transport requires energy; passive transport does not.
How does active transport differ from passive transport-?
Active transport requires energy while passive transport does not.
