Passive Transport, and if your dealing with liquids its is Osmosis.
Passive Transport is the act of transport with no use of energy: hence the word "Passive."
But Active Transport is when it does use energy: hence the word "Active."
Passive transport.
Energy is not required for passive transport, as it occurs naturally due to the concentration gradient without the cell expending energy. Examples of passive transport include simple diffusion, facilitated diffusion, and osmosis.
It's called passive transport for a cell's membrane. (I checked with my science teacher)

Passive transport is a process in cells where substances move across the cell membrane without requiring energy input. An example of passive transport is the movement of oxygen and carbon dioxide across the cell membrane through simple diffusion.
Diffusion is per definition a passive transport process.

Passive transport does not use energy to pass through a cell membrane. active transport uses energy to pass through a cell membrane.

active transport
It requires energy, and a protein carrier molecule. The large particle binds to the protein carrier on the inside of the cell. It is then transported across the membrane as a result of a conformational change in the protein (think of it flipping), and then it is released on the outside of the cell. Again, this requires some source of energy.
It's called active transport. When talking about the cell, it is usually bigger substances that use passages in the cell membrane to access the inner part of the cell, and they need energy to get there. The opposite; passive transport or diffusion, is the movement of dissolved materials through a cell membrane without the use of cellular energy. THis happens with smaller substances.
