Detailed explanation-1: -The xylem is an essential tissue in a vascular plant which is responsible for transport of water and minerals from the soil to different parts of the plant. It supports the plant and provides rigidity to the plant. 1. Xylem tracheids-These are dead tubes like hollow cells.
Detailed explanation-2: -Xylem is the specialised tissue of vascular plants that transports water and nutrients from the plant–soil interface to stems and leaves, and provides mechanical support and storage. The water-conducting function of xylem is one of the major distinguishing features of vascular plants.
Detailed explanation-3: -Both lignin and cellulose are found in the rigid cell walls of the xylem cells (those that conduct water) in the primitive plant Selaginella.
Detailed explanation-4: -Tracheids and vessels are the main elements for conducting water. Xylem fibres provide mechanical support and xylem parenchyma stores food materials and tannins and also conducts water radially.
Detailed explanation-5: -The correct answer is Transport of water from roots to leaves.
