What is Passive Transport?
Passive transport is the opposite of active transport. Cells move materials across a body through cell walls and cell membranes. The transport process is mainly of two types- Active transport and Passive Transport. Passive transport does not require any energy, the molecules just roll with the flow. Passive transport aids in the movement of nutrients like amino acids and glucose across an organism’s body.
In Active Transport, energy is needed to move molecules from one area to another. In active transport, molecules move from a region of low concentration to a high concentration with the help of the energy quotient, known as ATP. E.g. Nerve impulses are transmitted across the nervous system with the help of ATP.

Passive Transport
Passive transport is one of the techniques used for transportation in plants and animals. Transport usually occurs in two forms- Active transport and Passive transport. Active transport helps in the uphill movement of substances. On the other hand, passive transport helps in the downward movement of substances. There are four types of passive transport- diffusion, facilitated diffusion, osmosis, and filtration. In this article, we will study the definition of passive transport, types of passive transport, diagram, of passive transport, examples of passive transport, the difference between active transport and passive transport, and the importance of active transport.
