Which cells in corn plants have a function most similar to that of blood vessels in earthworms?

In corn plants, the cells that have a function most similar to blood vessels in earthworms are the xylem and phloem cells. The xylem transports water and minerals from the roots to the rest of the plant, akin to how blood vessels carry nutrients and oxygen in earthworms. The phloem, on the other hand, distributes sugars and other organic compounds produced through photosynthesis, similar to the role of blood in distributing nutrients throughout the earthworm's body. Together, these vascular tissues facilitate the transport of essential substances in plants, paralleling the circulatory function in earthworms.
