In xylem, tracheids and xylem vessels are placed end to end like tubes. How does this help plants?
Answer
In xylem, tracheids and xylem vessels are placed end to end like tubes. These cells are dead that means they don't have protoplasm. Thus it makes a clear straw-like passage for the easy movement of water and minerals in the plant. Also, these cells have lignified walls, which make their walls stiff, provide structural support and prevent the walls from collapsing during water transport.
