Explanation:
(a) Xylem parenchyma
The cells of xylem parenchyma are living and thin walled.
Their cell walls are composed of cellulose.
They store food materials in the form of starch or fat, and other
substances like tannins.
The radial conduction of water takes place by the ray
parenchymatous cells.
Primary xylem is of two types:
Protoxylem and metaxylem.
(b)Xylem fibres have highly thickened walls and obliterated central
lumens.
These may either be septate or aseptate.
