WebApr 5, 2024 · It is also called phellogen. It develops during the ongoing process of secondary growth. This meristematic tissue develops usually in the cortex region. The outer cells of phellogen differentiate into the cork or phellem while the inner cells differentiate into the secondary cortex or phelloderm. WebA ring of meristematic tissue formed by the dedifferentiation of outer cells of cortex (parenchyma) present in the general cortex of dicot stem, during extra stelar secondary growth. It is called Cork cambium or phellogen. So, the correct option ‘Outer cells of cortex’.
WebPhellogen or cork cambium is a type of cambium. It emerges inside the outer layer of the stems of woody plants, typically, as a complete ring that surrounds the inner tissues. The inner secondary cortex and outer corky tissue are …
WebTypically the phellogen first arises in or near the epidermis in a stem. Subsequent phellogens are formed as discontinuous, overlapping meristems, eventually in secondary phloem, but some exceptions to this generalization are known. The accumulation of periderm and included secondary phloem leads to our recognizing the rhytidome. … ipc cross platformWeb(A) Primary xylem and phloem differentiate from procambial tissue in the vascular bundles, and a fascicular cambium is formed from procambial tissue separating these tissues.

Anatomically it is termed as phellogen. 2. The permanent tissues of epidermis, cortex or phloem give rise to phellogen by dedifferentiation. 3.
