No, secondary phloem does not describe wood. Wood is primarily made up of secondary xylem, which is responsible for water conduction and structural support in plants. Secondary phloem, on the other hand, is involved in the transport of nutrients and sugars and is located just outside the secondary xylem in the plant stem.
What else can I help you with?
Is wood from a tree secondary or primary phloem?
Wood is primarily composed of secondary xylem, while phloem is the vascular tissue responsible for transporting nutrients. Trees produce primary phloem during their early growth stages, but as they mature, they develop secondary phloem through the activity of the vascular cambium. Therefore, while wood itself is not phloem, trees have both primary and secondary phloem for nutrient transport.
What term describes wood secondary xylem epidermal tissue primary vascular tissue or secondary phloem?
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 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 does the secondary phloem eventually become in trees?
The secondary phloem in trees eventually becomes crushed and functionally inactive due to the continuous production of new secondary phloem. Over time, it may also become part of the outer bark as the tree continues to grow in girth.

secondary xylem
What is the secondary meristem that produces wood toward the inside and bark toward the outside of a tree?
The secondary meristem that produces wood toward the inside and bark toward the outside of a tree is called the vascular cambium. It is a lateral meristem responsible for the secondary growth in plants, leading to the formation of secondary xylem (wood) and secondary phloem (bark).
What tissues make up wood and bark?
phellem(cork), phellogen(cork cambium), phelloderm(secondary cortex), primary phloem and secondary phloem constitutes BARK
What is the secondary meristem that produces wood toward the inside and bark toward the outside of a tee?
The secondary meristem responsible for producing wood toward the inside and bark toward the outside of a tree is called the cambium. Specifically, the vascular cambium is a layer of meristematic tissue that generates secondary xylem (wood) inward and secondary phloem (bark) outward. This process contributes to the growth in diameter of the tree trunk and enhances its structural support.
What does the secondary phloem eventually become in trees?
The secondary phloem in trees eventually becomes crushed and functionally inactive due to the continuous production of new secondary phloem. Over time, it may also become part of the outer bark as the tree continues to grow in girth.
What tissues arise from the active cell division of the vascular cambium?
The vascular cambium undergoes active cell division to produce secondary xylem (wood) towards the inside of the stem and secondary phloem towards the outside. This results in the growth of woody tissues in trees and other woody plants.
Difference between primary and secondary phloem?
Primary phloem 1. . Derived from procambium of apical meristem. 2. . District protophloem and metaphloem elements.3 Sieve tubes long and narrow. 3. Less or no development of phloem parenchyma. 4. Phloem fibres on the outer part. Secondary phloem 1. . Derived from vascular cambium. 2. . No clear demarcation between protophloems and metaphloems. 3. Sieve tubes short and wide. 4. .Well developed and abundant phloem parenchyma. 5. . Phloem fibers among the phloem parenchyma.
Is tree bark secondary phloem?
Tree bark is primarily composed of secondary phloem and cork, along with other layers. Secondary phloem is produced by the vascular cambium and is responsible for transporting nutrients and organic compounds throughout the tree. As the tree grows, older layers of phloem become part of the bark structure, while new layers continue to form. Thus, while bark includes secondary phloem, it also contains other components that contribute to its overall structure and function.
