Verified step by step guidance1
Understand the role of xylem tissue in plants. Xylem is a type of vascular tissue responsible for the transport of water and dissolved minerals from the roots to the rest of the plant.
Recognize that xylem tissue is composed of specialized cells, such as tracheids and vessel elements, which form tubes that facilitate the upward movement of water.
Consider the process of transpiration, where water evaporates from the leaves, creating a negative pressure that pulls water upward through the xylem.
Differentiate xylem from phloem, another type of vascular tissue, which primarily transports sugars and other organic nutrients from the leaves to other parts of the plant.
Note that while xylem does provide some structural support due to the lignin in its cell walls, its primary function is the transport of water and nutrients.
