Xylem |
Xylem vessels are involved in the movement of water from its roots to leaves |
The xylem is one of the two types of transport tissue in plants. The basic function of the Xylem is to transport water up the plant and to also carry nutrients, some of which are dissolved in the water.
The xylem is formed of columns of dead cells.
Features of the Xylem:
The xylem is formed of columns of dead cells.
Features of the Xylem:
- Cell walls are made of Lignin
- It is formed of dead cells
- It carries water and minerals to the leaves
- Impermeable, thick cell walls
- Only transports water and minerals
- The flow is upward
- There are no cytoplasm’s
- Tissue also contains fibres
The Xylem is found in all vascular plants and is also useful for supporting them. The Xylem also consists of a variety of specialized, water-conducting cells known as tracheary elements. The Xylem tracheary elements are made of cells known as tracheids. These are narrow, hollow and elongated - perfect for providing support because they are able to be stacked easily.
