Detailed explanation-1: -The xylem transports water and minerals from the roots up the plant stem and into the leaves.
Detailed explanation-2: -The direction of xylem transport is upwards and unidirectional i.e. from roots to other plant parts. The water column moves only upwards because of the two forces, transpirational pull, and positive root pressure.
Detailed explanation-3: -Xylem is one of the two types of transport tissue in vascular plants, the other being phloem. The basic function of xylem is to transport water from roots to stems and leaves, but it also transports nutrients.
Detailed explanation-4: -Water and solutes are transported by the xylem from the roots to the leaves, and food is transported from the leaves to the rest of the plant by the phloem. The process by which water evaporates from the leaves and draws more water from the roots is called ‘transpiration’.
Detailed explanation-5: -Xylem is unidirectional, whereas, phloem is bidirectional.
