The Vascular Cambium adds cells on both sides, producing secondary Xylem toward the inside of the stem
This is true for most vascular plants except for the order Myrtales that has phloem on both sides of the xylem. The cambium structure is quite different in this order.
primary xylem is primary in nature & is derived from procambium. But secondary xylem is secondary in nature and derived from fascicular cambium and interfascicular cambium. Primary xylem is differentiated into protoxylem and metaxylem, but secondary xylem has no such differentiation. In primary xylem vessels and tracheids are long and narrow, and vessels don't have tyloses, but in secondary xylem, vessels are blocked by tyloses, and vessels and tracheids are wider and shorter. Xylem fibres are more abundant in secondary xylem , and found in small numbers in primary xylem. Also unlike in primary xylem, secondary xylem has differentiated into sapwood & heartwood.
Secondary xylem
Vascular cambium
The primary growth in vascular plants takes place with the differentiation of vascular tissue from parenchymatous cells and the secondary growth takes place when the intra-vascular and inter vascular cambium adds to the secondary phloem and secondary xylem.
C. secondary xylemI'm positive its c. secondary xylem
Xylem
Xylem is a one way flow
They have different texture andstyle/ The woody stem has massive xylem tissue, mostly secondary in origin, the soft stem has a very little amount of stele.
secondary xylem
Meristematic tissue (vascular cambium) produces secondary growth. In plant stems, this serves to increase the diameter, and it forms between the primary xylem and phloem.
vascular cambium makes secondary xylem and phloem!!
