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 else can I help you with?
What is closest to the center of a woody stem?
Vascular cambium
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.
Where is most of the plant's new xylem and phloem produced?
Most of the plant's new xylem and phloem are produced in the vascular cambium, which is a thin layer of meristematic cells located between the xylem and phloem in the stem and root. This region is responsible for secondary growth in plants, leading to the production of new xylem towards the inside and new phloem towards the outside.
What is the growth of tissue that produces phloem and xylem in the stems of woody plants?
The growth of tissue that produces phloem and xylem in the stems of woody plants is called vascular cambium. It is a lateral meristem that produces secondary xylem (wood) towards the inside of the stem and secondary phloem towards the outside, allowing for the thickening and expansion of the stem over time.
The wood in the trunk and the limb of a tree is made up of?
The wood in the trunk and limb of a tree is made up of xylem tissue. Xylem is responsible for conducting water and nutrients from the roots to the rest of the tree. It also provides structural support to the tree.
What term describes wood secondary xylem epidermal tissue primary vascular tissue or secondary phloem?
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

pith
What terms can describe wood?
secondary xylem
What terms describes woods?
secondary xylem
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.
What are the different types of secondary growth in dicots?
1. Normal type of secondary growth in the cortical and vascular regions adding to the secondary xylem ,secondary phloem and periderm at their proper places 2. Various types of anomalous secondary growth putting paches of xylem & phloem abnormally.
What is the wood in the trunk and limbs of a tree made of?
Secondary Xylem
What arises from lateral meristem activity?
secondary xylem and phloem.
What type of plant tissue makes up wood?
Wood is primarily composed of xylem tissue, specifically secondary xylem. Secondary xylem is responsible for providing structural support and conducting water and nutrients throughout the plant. Wood also contains other tissues such as ray cells and bark.
What fibers surround the xylem tissues?
Fibers made of long, narrow, sclerenchyma cells with thick secondary walls surround the xylem tissue. They provide strength and support to the xylem tissue.
