What is xylem parenchyma?
Answers
Answer:
the main functions of xylem parenchyma include: Storage of food material in the form of starch, fats, tannins and crystals.
Explanation:
Answer:
Xylem Parenchyma: Only living cells of xylem and store starch and fat. They assist in the short distance transportation of water.
Structure of Xylem Parenchyma
Parenchyma cells associated with xylem are called “xylem parenchyma”.
There are two major types of parenchyma cells in secondary xylem
Axial parenchyma cells arranged around the axis
Radial parenchyma cells arranged like a ray, radiating out of the common centre.
Functions of Xylem Parenchyma
The main functions of xylem parenchyma include:
Storage of food material in the form of starch, fats, tannins and crystals
Radial conduction of water takes place by the ray parenchymatous cell
Xylem parenchyma cells are closely connected to vessels or tracheids through outgrowths called tyloses
During drought or infection, these tyloses help to prevent damage of vascular tissues
Xylem parenchyma cells are involved in the maintenance of xylem transport capacity
They are responsible for the restoration of vessels and tracheids functionality when there is blockage of the cavity due to the air bubble (embolism). Cavitation occurs due to the high tension of water in the xylem tissues
