Why Xylem is a tissue?
Tommy, xylem is a tissue not an organ because it fits the definition of a tissue , similar cells joined together to preform specific functions, but not an organ, group of many different tissues joined together to perform several functions. The xylem has only one function … to transport water upward in the plant.

What is xylem tissue class 9?
Answer: Xylem is a complex permanent tissue found in all parts such as the root, stem and leaf of the higher plants. It is made up of four types of cells out of which one is living (xylem parenchyma) and three are dead (vessels, tracheids and xylem fibres). These provide strength to the plant organs.
What is the main function of xylem and phloem?
What are the functions of xylem and phloem? Xylem and phloem facilitate the transportation of water, minerals and food throughout the plant. Xylem carries water and minerals from the roots to the leaves. Whereas, phloem carries the food prepared by the leaves to different parts of the plant.
Where is the xylem located?
Xylem can be found: in vascular bundles, present in non-woody plants and non-woody parts of woody plants. in secondary xylem, laid down by a meristem called the vascular cambium in woody plants. as part of a stelar arrangement not divided into bundles, as in many ferns.
Can xylem vessels be blocked by air bubbles?
The blocking of a xylem vessel or tracheid by an air bubble or cavity is called as embolism (Gr. The mature vessels or tracheids (which are dead and consist of only thick cell walls) are compactly packed and form conduits for the upward movement of water through them.
What is Apoplastic pathway?
The apoplastic pathway is one of the two main pathways for water transport in plants, the other being symplastic pathway. In apoplastic transport, water and minerals flow in an upward direction via the apoplast to the xylem in the root.

A Center of Excellence (CoE) is a body in an organization that works across business units (BUs) or product lines within a BU and has a leading-edge knowledge and competency in that area.

What is the function of xylem and it’s components?
| Type | Function |
|---|---|
| Components of Xylem | |
| Tracheids | Provide a network of hollow connected cells for the transport of water. Provide mechanical support by developing various types of thickenings in their walls. |
| Xylem vessels | Allow free flow of water and minerals in a vertical direction from the roots to the leaves. |
| Xylem parenchyma | |
What is the importance of excellence?
Many people around us who do not strive for excellence, have hard time and do not feel happy with their lives. While people who always strive for excellence, feel happy, have inner satisfaction and contribute positively to others as well, thus excellence is the condition of surpassing some standards of expectations.
Which of the following components of xylem is living?
Answer. Only Xylem Parenchyma is living other components i.e. tracheids, vessels, fibres are dead.
How do you achieve personal excellence?

How do you describe academic performance?
Academic performance is the measurement of student achievement across various academic subjects. Teachers and education officials typically measure achievement using classroom performance, graduation rates and results from standardized tests.
Which elements in phloem are living cells?
Living elements of phloem are sieve tubes, companion cells and phloem parenchyma.
Is xylem a cell?
Xylem consists of dead cells. The cells that make up the xylem are adapted to their function: They lose their end walls so the xylem forms a continuous, hollow tube. They become strengthened by a substance called lignin .
What are the components of xylem?
The structural elements of xylem are tracheids, vessels or tracheae, xylem fibres, xylem parenchyma and rays. The tracheid is derived from a single cell and can be regarded as the basic cell type of xylem tissue.
What is the main function of xylem within a plant?
Xylem, plant vascular tissue that conveys water and dissolved minerals from the roots to the rest of the plant and also provides physical support. Xylem tissue consists of a variety of specialized, water-conducting cells known as tracheary elements.
What are the types of xylem cells?
Definition of Xylem: Xylem can be defined as a complex tissue that is composed of four basic types of cell (tracheids, trachea, and xylem fibre and xylem parenchyma), remains in close association with phloem and has specialized functions like conduction of water and solutes, and mechanical strength.
What are the four components of phloem?
Phloem is composed of various specialized cells called sieve tubes, companion cells, phloem fibres, and phloem parenchyma cells.
How do you demonstrate academic excellence?
The Secret To Achieving Excellence In Academics
- Hunger for knowledge. The drive and hunger to achieve one’s goal is what makes one look forward, and encourages him or her to strive for it every day.
- Raise your target level. Raising your benchmark will actually help to make you more competitive.
- Have faith in yourself.
- Do not give up.

What are the components of excellence?
Human excellence in virtually all domains is guided by mental factors. The experiences of exceptional performers suggest that there are seven critical elements of excellence: Commitment, Belief, Full Focus, Positive Images, Mental Readiness, Distraction Control and Constructive Evaluation.
How is xylem tissue formed?
Xylem tissue forms from cells that are derived from meristematic cells commonly called procambium and cambium. These meristems contain pluripotent stem cells which have the ability to continuously divide and maintain the stem cell population, a so‐called ‘stem cell niche’ (Miyashima et al., 2013).
Where is xylem and phloem located?
In stems and roots, the xylem typically lies closer to the interior of the stem with phloem towards the exterior of the stem. In the stems of some Asterales dicots, there may be phloem located inwardly from the xylem as well. Between the xylem and phloem is a meristem called the vascular cambium.
What is an example of xylem?
Xylem is a type of tissue in plants that carries water. An example of xylem is what moves water and some nutrients through a plant. In a tree trunk, the innermost part of the wood is dead but structurally strong xylem, while the outer part consists of living xylem, and beyond it, layers of cambium and phloem.
