Radial conduction of water takes place by
Options
(a) vessels
(b) vessels and tracheids
(c) phloem
(d) ray parenchyma cells
Correct Answer:
ray parenchyma cells
Explanation:
Ray parenchyma cells are the living components of otherwise dead tissue xylem. They are found in secondary xylem and form the part of radial/horizontal system. They usually contain starch, crystal or other ergastic substances. Sometimes the cells of xylem parenchyma have pitted walls. They act as storage as well as conducting tissue and help in radial conduction of water.
