Phellem or cork is a tissue formed on the outer side of cork cambium . It is composed of dead cells. The cell walll become impermeabel due to suberisation.
Step-by-Step Solution:1. Understanding Xylem Fibres: Xylem fibres are specialized cells found in the xylem, which is a type of vascular tissue in plants responsible for the transport of water and nutrients from
Phloem is a type of plant tissue. Along with its counterpart, xylem, phloem allows plants to...
Vascular plants are those which have specialized tissue for transport for water, minerals and food. These specialized tissues in vascular plants are the xylem and phloem. Answer and Explanation:1 Phloem is the vascular tissue responsible for the transportation of synthesized food in plants. It is ...
and parenchyma cells with different functions are present. Tracheary elements in xylem are dead at maturity, while sieve elements in phloem are still-living cells lacking certain organelles, such as nuclei, mitochondria, and plastids [5]. The unique characteristics and heterogeneity of vascular tissue...
Young people, and the young at heart, ask great questions. But sometimes, the endless questions run into bigger answers than anyone expects. What's that tree made of? Leaves and bark, xylem and phloem, and cambium. What are those made of? Cells, molecules,carbonatoms. But what's an ato...
What stimulates growth in the vascular cambium? Is auxin produced in the vascular cambium? How does vascular tissue differ in herbaceous and woody plants? How do the cells of the xylem compare to the cells of the phloem? What is the role of xylem in a vascular plant?
Heartwood is the dead, inner layers of wood in the tree which no longer transport water. ... Heartwood forms in the transition zonewhen the ray cells die and deposit chemical extractives in the surrounding xylem. These chemicals convey natural durability which is of value to the forest and ...
Are phloem cells dead? Unlike xylem (which is composed primarily of dead cells), the phloem iscomposed of still-living cellsthat transport sap. The sap is a water-based solution, but rich in sugars made by photosynthesis. What is lignin made up of?
Organisms/organs are made of cells. Cells are 70% water. If that water is not replaced, cells shrink and eventually die. All cell activity requires water for transport of the necessary ingestion of needed chemicals (ATP, minerals, enzymes, etc.) and excretion of matter that is ...
