Permanent fabric

from Wikipedia, the free encyclopedia

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.

Finishing fabric

The closing tissues in plants serve to protect the plant. They are the outer skin of the plant. Finishing fabrics are:

Strengthening fabric

Strengthening tissues hold the plant in place, there are the following types:

Base fabric

The basic tissue stores water , starch , fats and proteins . It arises from cells of the palisade / sponge tissue (in the leaf). Examples are:

Conductive tissue

Conductive tissues are responsible for the transport in the plant.

  • Phloem transports the photosynthetic products.
  • Xylem is responsible for transporting water and minerals.
