To define Xylem, it is a transport tissue found in vascular plants along with phloem. The important function of xylem is to transport nutrients and water to leaves and stems from roots and also to provide support. The Xylem word was introduced by Carl Nageli in 1858. Now let us see the xylem diagram so that we can have a basic idea of xylem structure. Xylem Diagram (Image will be Uploaded Soon) (Image will be Uploaded Soon) Types of Xylem Xylem is mainly of two types: primary and secondary. They both perform the same function but they are categorized depending on the type of growth. • Primary Xylem: It will be formed with the primary growth of the plant. This growth can be found in the tips of the stems, roots and flower buds. This will make the plants grow taller and roots to grow longer. This is known as primary growth because it occurs first in the growing season. • Secondary Xylem: This will be formed with the plant’s secondary growth and this will allow the plant to grow wider by the time. For example, wide tree trunks which show a lot of secondary growth. It will occur every year after primary growth. Secondary xylem is responsible for tree trunks' dark rings which are used to determine the age of the tree. The two main groups of Plantae in which secondary xylem can be found are conifers and angiosperms . What are the Components of Xylem? Xylem is composed of mainly four types of cell in which some of them are living and some of them are dead. • Tracheids: These are ...
