Question

Why is lignin present in xylem?

Answer 1

X xylem:

1. Xylem vessels transport water and minerals upwards through the plant stem.
2. It comprises dead and empty cells.
3. Its walls are lignified which permits it to endure pressure changes as water moves.
4. Lignin, which is a complicated natural polymer that offers primary help to the tissues of vascular plants.
5. Bark and wood have lignins in their cell walls because they give them stiffness.
6. Since it is lipophilic (lipid soluble) but hydrophobic (water insoluble), it prevents water from passing through.
7. Thus, lignin facilitates the conductivity of water through vascular tissues.
