Diffusion and osmosis ( movement of molecules from higher concentration to lower concentration until evenly spread.)
Passive transport... the opposite of active transport.
Passive transport is the cellular transport mechanism. This all depends on the blood pressure.
Passive transport
Two main categories are active and passive transport.
The 2 transporters of cellular energy are passive and active transport.

No, diffusion is passive transport.Active transport would be when there are actual proteins and structures involved in the transportation of molecules/chemicals/etc..A sure sign is that all of these (that I know of) require ATP.An example would be the Sodium-Potassium Pump located along one's neurons which actively pumps (aka. transports) sodium and potassium back and forth across the membrane to build up potential charge. This is how "signals" are sent down neurons and around the body.
Osmosis does not require ATP so it is a passive transport.Osmosis is a form of passive transport. Water molecules are small enough to move freely across the plasma membrane without the use of cellular energy.
The movement of materials across the cell membrane without using cellular energy is called passive transport. The movement of materials against a concentration difference is known as active transport. Active transport requires energy.
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.
Active transport requires energy; passive transport does not.
Yes. it has to use energy to go throught the cell membrane
