What is the role of xylem parenchyma?
A
To store food and tannin deposits, which protects from herbivore attack
B
To contain salts which are then transported in the xylem
C
To allow exchange of substances between the xylem and the phloem
D
To give additional support to the plant
Explanation: 

Detailed explanation-1: -Xylem parenchyma cells can store water, which is essential for the proper functioning of a plant. Water stored in the living cells of wood is a fraction of intracellular water storage, which also includes the cells of the pith and the layers outside the vascular cambium, such as phloem [70].

Detailed explanation-2: -Xylem parenchyma is made up of parenchymatous cells with thin walls. These cells are living. The main function of xylem parenchyma is to store food in the form of starch.

Detailed explanation-3: -Xylem parenchyma is the only living xylem element that stores food in the starch form, fat form, tannins, and crystals.

Detailed explanation-4: -Parenchyma cells store food material in the form of oil, fats, proteins, and starch, for example, parenchymatous tissues in roots and stem tubers. So, parenchyma is a simple permanent tissue that helps in storing food in plants.
