Both
You'll have to be more specific. It can be either. The distinguishing feature is that active transport requires energy to occur, passive does not
active transport
There is no movement in any described genus of pitcher plant. All are entirely passive.
Active transport need energy from outside to perform a function whereas in passive transport the function is performed on the principle of physics. for example active absorption of minerals by the plant roots require energy from respiration whereas passive absorption is achieved by law of diffusion.
Active transport requires energy, passive transport just happens. If there is more of a certain molecule on one side of a membrane than the other, molecules that CAN fit through the membrane will do, so the concentration will even itself out. No work has to be done to achieve this. SO when you breathe in, oxygen just diffuses across from the air into your blood, because there's plenty of it in the air. But if a plant needs to get say magnesium from the soil (which it needs to make chlorophyll) then it is not going to get much by diffusion, because there's not much in the soil and probably more in the plant. It will need to use active transport ie a protein in the cell wall will pick up the substance wanted and flip it into the cell, and this costs the cell some energy.
Plants employ osmosis to move minerals into plant root cells. To transport minerals to the plant proper, energy is required so active transport is employed.
It is a plant that catches prey without moving.
Perhaps the gratest benefit of transpiration is that it uses solar energy to drive passive movement of water and minerals from soil to leaves. The plant does not expend energy moving this water.
Osmosis moves water (only) on a concentration gradient, from a high concentration to a low concentration. Active trasnport is the forced movement of chemicals via particular proteins which move when TCP is near.
