Passive (just guessing)
The most basic difference between active and passive transport is that active requires energy while passive does not. You would require active transport if the substance is going against the concentration of molecules inside and outside of the membrane or if the substance is particularly large. Passive is more for smaller molecules that go with the concentration of the molecules inside and outside of the membrane.

Trans-membrane proteins that can be used for active or passive transport of material into and out of the cell.
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.
An active system has amplifiers and electronic crossover built in to the cabinet. A passive system has just the speakers and possibly a passive crossover (made up of capacitors and inductors) inside the cabinet. A passive system requires external amplifier(s) to work.
there are two ways to transport things into a cell: active and passive transport. In active transport the cell has to physical engulf whatever it needs from outside the cell. In passive transport, if something inside the cell has less of the item that is outside of the cell, the things outside of the cell go into the cell until the number is balanced. This happens automatically so it doesn't involve energy.
It would be active transport, a process which requires a cell to use its own energy (unlike passive transport).
Vesicular active transport
Active transport
Chlamydia becomes active as soon as it enters the body.
Volcanologists work both inside and outside. They study rocks in laboratories and they often visit active volcanoes to take measurements and samples.
