Permanent tissues are tissues in plants that are no longer capable of dividing. Normally, there are no more cell divisions in permanent tissues , their differentiated cells are no longer capable of growth and often even dead, containing water or air. The open organization of the plant body means that large, perennial plants contain many dead cells. For example, in the trunk of an older tree, the proportion of living cells is minimal, while wood, secondary phloem and covering tissue consist predominantly of dead cells.
The closing tissues in plants serve to protect the plant. They are the outer skin of the plant. Finishing fabrics are:
Strengthening tissues hold the plant in place, there are the following types:
Conductive tissues are responsible for the transport in the plant.
- Phloem transports the photosynthetic products.
- Xylem is responsible for transporting water and minerals.
