Diffusion is an example of passive transport because an organism need not expend energy to accomplish diffusion. In diffusion, molecules simply cross a membrane from an area of higher concentration to an area of lower concentration.
Because it does not require the input of any energy for it to take place. Diffusion is just the movement of particles from a region of higher concentration to a region of lower concentration, something they tend to do on their own.
Active transport is like a person climbing a wall passive is another person going through the open door see?!?A process known as passive transport helps molecules to diffuse across a membrane. Passive transport does not involve the use of chemical energy, unlike active transport does.

Passive transport is not an example of essential nutrients for the cell.

Diffusion is an example of passive transport, like osmosis(the diffusion of water through a membrane).
Endocytosis is an example of active transport.
passive transport
Passive transport refers to the movement of molecules across a cell membrane. An example of a sentence would be: "Passive transport does not require energy to work".
yes it is
Proteins that carry out passive transport include channel proteins and carrier proteins. Passive transport is "passive" because it does not use energy. The use of passive transport is also called "facilitated diffusion." Proteins that carry out passive transport includes the proton pump and the sodium-potassium pump; these require energy to function.
The only different between passive and active transport is the use of energy. In passive transport, molecules can either diffuse across the membrane, go through an aquaporin or use a passive transporter. In active transport, energy needs to be released, and it is usually because you are trying to transport a molecule or ion up its concentration gradient.
Osmosis is an example of Passive Transport.
