Question

Tracheids or sieve cell (which one is xylem element?)​

Answer 1

$\blue{ \Large{\boxed{ \tt{ \red{Answer : }}}}}$

• Tracheids are elongated cells in the xylem of vascular plants that serve in the transport of water and mineral salts. Tracheids are one of two types of tracheary elements, vessel elements being the other. Tracheids, unlike vessel elements, do not have perforation plates.

Answer 2

Tracheids and vessel elements: Tracheids (top) and vessel elements (bottom) are the water conducting cells of xylem tissue. The substances travel along sieve elements, but other types of cells are also present: the companion cells, parenchyma cells, and fibers.
