Vasculature

Across many land plants, similar cells and cell structures relating to similar functions can be identified. One of which being vascular components. A plant's vascular system can be broken down into two major groups, xylem, and phloem. Xylem are plant cells designed to transport water from the roots to the shoots via a suction pump of sorts. As the plant uses its water at a sink, place where water is used, it creates a low-pressure zone which in turn creates a pressure gradient. This gradient of high to low is what ultimately runs the movement of water in a plant. Xylem can be found near the inside of plants and in woody plants, they are actually dead. As a part of their development, they die so the plant doesn't need to spend much energy on them and it can gain structure from having many tightly packed xylem.

Phloem are the food transport cells of a plant. These are living cells whose main purpose is to facilitate the transport of sugars and foodstuffs from the leaves where sugars are created to sinks, where sugars are used, such as shoot apical meristems, root meristems, and cambial meristems. As a side, meristems are undifferentiated cells who create mature cells to replace older ones. Phloem are entirely hollow, to allow for efficient transport, however, still require 'helper' cells connected by plasmodesmata to house the necessary organelles for them to survive. Xylem and phloem work together to form the vascular system found in all vascular plants.
