Detailed explanation-1: -Xylem fiber transports water and provides mechanical support. Xylem parenchyma is the only living xylem element that stores food in the starch form, fat form, tannins, and crystals.

Detailed explanation-2: -The only part of the plant that does not store food is the reproductive part. The reproductive part of a plant is called a flower. It is specialized to perform reproduction.

Detailed explanation-3: -Complete answer: Non-vascular plants are those plants which lack xylem and phloem. Xylem and phloem are together called a vascular system. The xylem tissue helps in the conduction of water whereas the phloem regulates the function of conducting nutrients and minerals to the plant.

Detailed explanation-4: -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].
