What is the common name for secondary xylem?
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.
What term describes wood secondary xylem epidermal tissue primary vascular tissue or secondary phloem?
Secondary xylem
What is closest to the center of a woody stem?
Vascular cambium
What structures does this vascular cambium produce and where are they produced?
The vascular cambium produces secondary xylem (wood) and secondary phloem, which are formed in a lateral direction. These structures are produced between the primary xylem and primary phloem in stems and roots of plants. The secondary xylem is produced toward the interior, while the secondary phloem is produced toward the exterior, contributing to the increase in girth of the plant.
What is precambium?
The precambium is a layer of meristematic tissue found between the primary xylem and phloem in vascular plants. It is responsible for the production of secondary vascular tissue in the form of secondary xylem (wood) and secondary phloem.
Leaves dont have secondary xylem and phloem why not?
Leaves are designed to last only a short time so a secondary xylem and phloem supply is not needed. These chemicals offer a strong support system that is not needed in the leaves, just the trees.
What is meat by primary and secondary growth in vascular plants?
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.
The wood in the trunk and limbs of a tree is made up of?
C. secondary xylemI'm positive its c. secondary xylem
How does xylem differ from phlegm?
Xylem is a one way flow
What part of a plant produces secondary growth?
The vascular cambium, a layer of cells between the xylem and phloem tissues in the stem, is responsible for producing secondary growth in plants. This results in the thickening of the stem and roots as new layers of xylem and phloem are added.
What tissue is responsible for forming secondary xylem and phloem in terrestrial perennial plants?
Xylem is part of the vascular tissue of plants, and the xylem and phloem together are grouped together as the stele (latin for 'pillar'). Xylem tissue is encased in lignin, the substance that creates the strength of wood, causing the protoplasm (living part of the cell) to die, and therefore be dead tissue; phloem is living tissue.
