Direction of Transport in Plants

Plants move water, minerals, organic nutrients and growth regulators over long distances without an animal-like circulatory system.

Which plant transport is always upward in the source?

Xylem movement is always upwards and unidirectional.

Direction	Source-backed recall
Unidirectional	Water and minerals move in xylem from roots to stems and leaves.
Multidirectional	Photosynthates and mineral nutrients are transported in different directions.
Polarized or unidirectional	Plant hormones and chemical stimuli may move from where they are synthesised to other parts.
