Detailed explanation-1: -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.

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 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-4: -Phloem parenchyma is made up of thin walled elongated cells. It takes part in lateral conduction of water and storage of food.

Detailed explanation-5: -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.
