Active transport is a very important process, as it is required by the cells to maintain their normal state of homeostasis. This process often takes place inside the internal lining of the small intestine. In plants, there is a need to absorb mineral salts from the soil, but these salts exist in a minimum concentration.

By this method, water and minerals reach the different part of the body of the big plant. In the night the rate of transpiration is low, hence in night water and mineral transportation takes place by root pressure. Translocation: Glucose is made in the leaves during the day in presence of sunlight by the process called photosynthesis.
the transport system or a vascular wonder of a higher plant consists of xylem and phloem tissues . xylem carry water and Minerals upward from the route to the leaves while phloem carry food manufactured by the leaf to different part of the plant for utilisation and storage .
Movement of Mineral Ions. From roots, minerals are then transported to all the other parts by transpiration pull. Minerals are required in more quantity by all the growing parts. Minerals from the older parts also get transported to the new parts. For example, minerals from old leaves are transported to other parts when they are about to fall.
In the xylem, minerals are carried up along with the flow of xylem solution. In leaves the cells absorb the minerals selectively through membrane pumps. Translocation of Mineral Ions in the Plant: Though it is generally considered that xylem transports inorganic nutrients while phloem transports organic nutrients, the same is not exactly true.
During transportation, water preferentially carries away small particles in the process called washing. Wind does the same in the process called winnowing. The material not carried away may be left behind as a lag deposit or a pavement. Transportation and weathering are the two phases of erosion.
