Primary xylem

The key difference between primary xylem and secondary xylem is that the procambium forms the primary xylem during the primary growth, while the vascular cambium forms the secondary xylem during the secondary growth.. Xylem and phloem are the main types of complex tissues in plants. The xylem tissue in higher vascular plants transport water and dissolved minerals across the plant through.

Vascular Cambium - Origin... Vascular cambium arises from the primary meristem, procambium that remains undifferentiated between the primary xylem and primary phloem represent a continuous ring which bisects the primary xylem and primary phloem The vascular cambium then produces secondary xylem on the inside of the ring, and secondary phloem on the outside, pushing the primary xylem. The cells of the secondary xylem contain lignin, the primary component of wood, which provides hardiness and strength. The xylem together with the pith form the wood of a woody stem.

Xylem - Wikipedi

Xylem maturation is the pattern formed when xylem cells mature, as observed in transectional area. These xylem cells are formed from the apical cells/meristem (=primary xylem). Maturation patterns can be ascertained by locating the position of protoxylem and metaxylem cells Internal phloem is mostly primary, and begins differentiation later than the external phloem and protoxylem, though it is not without exceptions. In some other families ( Amaranthaceae , Nyctaginaceae , Salvadoraceae ), the cambium also periodically forms inward strands or layers of phloem, embedded in the xylem: Such phloem strands are called included or interxylary phloem
