Complex Permanent Tissue
Complex permanent tissues are made up of different kind of specialized cells that work together to perform specific functions within a plant. It help in the transportation of food, water, and minerals throughout the plant.
Xylem
It is mostly made up of dead cells and is used to transport water and mineral from root to leaves and other parts of the plant. It consists of various cell types, including tracheids and vessel elements for water conduction, fibers for support, and xylem parenchyma cells for storage. Only, the Xylem parenchymas is made up of living cells and contains food. The tracheid and vessels are long, elongated, and hollow.
Phloem
Phloem is composed of living cells and helps in the transportation of food from leaves to other parts of plants. It is made up of sieve tube elements, which are responsible for transporting nutrients, and companion cells that support sieve tube elements, phloem fiber, and phloem parenchyma. Only phloem fiber is made up of dead cells. They are also responsible for the transportation of proteins and mRNAs.
Permanent Tissues – Diagram, Types Notes Biology Class 9
Permanent tissues are a type of plant tissue that has completed its growth and differentiation. They remain in a specialized state throughout the plant’s life. These tissues perform specific functions and are responsible for the overall structural growth and function of the plant. There are three main types of permanent tissues in plants: Parenchyma, Collenchyma, and Sclerenchyma.
