What is the primary function of the xylem tissue in plants?
To transport water and minerals obtained from the soil
Xylem is a complex conducting tissue made of tracheids, vessels, xylem parenchyma and xylem fibres. Its primary function is to transport water and dissolved minerals absorbed by the roots from the soil upward to the stem and leaves.
This upward movement is driven mainly by transpiration pull, helped by root pressure and capillarity. Its thick lignified walls also give mechanical support to the plant.
Carrying the products of photosynthesis (food) from leaves to other parts is the job of phloem (translocation). Energy comes from cellular respiration, and glucose is synthesised in the chloroplasts of leaf cells during photosynthesis, not by xylem.
Hence, the answer is To transport water and minerals obtained from the soil.
