Which Is Transported In The Xylem Of A Plant Apex. Hormones and other small molecules also travel through the xylem as they are moved throughout the plant. The phloem and xylem are the main tissues responsible for this movement.

This also allows minerals absorbed from the soil to be transported through the xylem to the leaves water molecules cling together by hydrogen bonds between the molecules. The mechanism of phloem transport remains unclear ( see below ). The main function of xylem is to transport water, and some soluble nutrients including minerals and inorganic ions, upwards from the roots to the rest of the plant.

Xylem is made up of 4 kinds of cells:tracheids,vessels,xylem parenchyma,xylem fibres. The water and minerals are absorbed by plants from the soil through root hairs and root apex. Also, potassium participates in creating the turgor gradient. Some trees can lift water over distances of more than 100 metres from the roots to the uppermost leaves (ryan et al., 2006).
