Walls have been built by various civilizations throughout history for different purposes, such as protection, defense, and delineation of borders. Some of the earliest known walls were built by the ancient civilizations of Mesopotamia and Egypt around 3500 BCE for defense against enemies and natural elements. The construction of walls has continued over time, with examples like the Great Wall of China, built in different phases starting around the 7th century BCE.

Xylem has thick walls, which are reinforced by lignin, providing structural support and facilitating the transport of water and minerals from the roots to the rest of the plant. These thick walls help prevent collapse under negative pressure created during water transport. In contrast, phloem, which transports sugars, has thinner walls.
