In a girdled plant, when water is supplied to the leaves above the girdle, leaves may remain green for sometime because leaves can synthesise their own carbohydrate food through photosynthesis, then wilt due to non-availability of water.
The system of xylem vessels from root to the leaf vein can supply the needed water, during girdling there is a possible loss of xylem vessels and the water supply cuts off, resulting in death of plant.

I. Carrier proteins are needed for both facilitated diffusion and active transport and are sensitive to inhibitors that react with protein side chains.
II. Different types of proteins present in the membrane play a major role in both active as well as passive transport.
III. The carrier proteins needed by facilitated and active transport are specific.
IV. There is no need of energy to pump molecules against a concentration in active transport.
V. Transport rate reaches a saturation point, when all the active proteins are used.
