Answer 1

Answer:

Companion cells are living cells that are connected to the sieve-tube members of the phloem through plasmodesmata. The xylem fibers are non-living sclerenchyma cells as they lose their protoplast at maturity. These cells are found in between the tracheids and xylem vessels of the xylem tissue. Sclerenchyma cells are narrow and elongated cells with tapering ends. They are former parenchyma cells that developed secondary cell walls.
