Plant transport various substances like gases, minerals, water, hormone and organic solutes to short distance (one cell to another) or long distance as water from roots to tips of stem.
- Long distance transport occurs through vascular system, xylem and phloem called translocation through mass flow.
- The direction of translocation may be unidirectional as in case of water and multidirectional as in minerals and organic solutes.
- Simple Diffusion
- Facilitated Diffusion
- Active Transport
