Phelloderm

The phelloderm ( cork bark ) is a parenchymatic tissue in the outer shoot area of the plant. It is formed by the neighboring phellogen ("cork cambium"), which releases phelloderm cells to the inside and also newly formed phellem cells ("cork") to the outside. The phelloderm, together with the phellogen and the phellem, forms the periderm , a secondary closure tissue of the shoot.

The biologically active phelloderm cells have thin, less lignified cell walls in accordance with the parenchymatic character of this tissue . They are rich in plasma , often contain chloroplasts, and are relatively large. There are larger intercellular spaces in the tissue association .
