Compare and contrast xylem and phloem
Xylem and phloem are two types of vascular tissue found in plants. They are responsible for transporting water, nutrients, and sugars throughout the plant, and they play a vital role in the overall health and function of the plant. While xylem and phloem are similar in their role in plant transport, they differ in their structure and function.
One of the main differences between xylem and phloem is their function. Xylem is responsible for the transport of water and minerals from the roots to the rest of the plant. It consists of tubes made of dead cells, called tracheids and vessel elements, which transport water and minerals up through the plant. The xylem is also responsible for providing structural support to the plant, as the tubes are held together by lignin, a tough, woody material.
On the other hand, phloem is responsible for the transport of sugars and other organic compounds throughout the plant. It consists of living cells called sieve tubes and companion cells, which transport sugars from the leaves, where they are produced through photosynthesis, to the rest of the plant. Phloem also plays a role in the storage of excess sugars and nutrients in the roots, stems, and leaves of the plant.
Another key difference between xylem and phloem is their structure. As mentioned earlier, xylem consists of tubes made of dead cells, while phloem consists of living cells. This means that xylem does not have the ability to regenerate, while phloem can regenerate if damaged. Additionally, xylem cells are larger and more rigid than phloem cells, due to the presence of lignin. Phloem cells, on the other hand, are smaller and more flexible, which allows them to transport sugars and other organic compounds more easily.
In terms of location in the plant, xylem and phloem are also distinct. Xylem is found in the vascular tissue of the plant, and is typically located closer to the center of the plant. Phloem, on the other hand, is found in the outer layers of the plant, and is typically located closer to the surface.
Overall, xylem and phloem are two important types of vascular tissue in plants that play a vital role in the transport and distribution of water, minerals, and sugars throughout the plant. While they have some similarities in their function, they differ in their structure, location, and the types of substances they transport. Understanding the differences between these two types of vascular tissue is important for understanding the overall function and health of plants.
Phloem vs Xylem
Fibres Xylem fibres are smaller. Xylem tissues are composed mainly of dead cells. Plasmodesmata pass through these sieve plates and into the cell walls apoplast pathway which make contact with both the cytoplasm symplast pathway of companion cells and the sieve elements. Types of Phloem We can differentiate Phloem as protophloem and metaphlem. Xylem often constitutes the bulk of the plant body. You can get a free PDF download for xylem and phloem revision notes and important questions with Vedantu.

To get answers to all the questions relating to the topic xylem and phloem, students can refer to the study material provided by the best online learning portal Vedantu that has years of experience in providing the best study material to students to help them score well in their exams and prepare for a bright future. Differentiation of procambium followed by primary phloem and then primary xylem. Â Xylem and Phloem Xylem and Phloem are two different types of vascular tissues, which are mainly involved in the transportation process. To view the purposes they believe they have legitimate interest for, or to object to this data processing use the vendor list link below. There are a variety of other cells giving it the status of complex tissue. This is calle girdling, but such a process has no Types of plant cells Anonymous comments 5 April 20, 2014, 6:10pm great information — 37. Complete answer: Xylem is a conducting tissue that is responsible for the transport of water while a phloem is a conducting tissue that is responsible for the transport of food in plants.

An example of data being processed may be a unique identifier stored in a cookie. Materials Xylem consists of fibers, xylem vessels, and tracheids. There are several similarities with the transport of water, in each case liquid moves by mass flow along a pressure gradient through tubes formed by cells stacked end to end. Phloem includes phloem parenchyma and fibers, companion cells, intermediary cells, sieve tubes, and bast fibers. Whereas the phloem aids the translocation of photosynthesized food material from the source to the other part. Importance of Xylem and Phloem The vascular tissues of the plant Xylem and phloem are very important tissues of the plant because of which the water and food are transferred from one part to other parts of the plant. You can rely on the study material and prepare well for your exams as it is prepared by the expert teachers of Vedantu who have deep knowledge of every topic to provide you with error-free study material.
Compare and contrast the forces that move phloem sap and xylem sap over long distances.
In contrast to the structure of the xylem vessels, the sieve-tube elements have end walls which are arranged adjacently to form sieve tubes, the actual conducting element. It consists of four elements: companion cells, sieve tubes, bast fibres, phloem fibres, intermediary cells and the phloem parenchyma. The xylem cells are lengthy tracheary components important for water transfer. The major conduits through which food items pass in a vascular plant are sieve tubes, which seem to be a column of sieve tube cells. Conducting Cells The conducting cells in the xylem is dead.
compare and contrast the following xylem and phloem
Let us now understand and find the difference between xylem and phloem. Does not provide mechanical support. Xylem is responsible for the movement of water and minerals in the plant body. Vessel components are shorter and are linked together in tubes known as vessels. The food generated in the source organs is efficiently carried to the sink organs for their sustainable growth. Phloem refers to the living tissue which helps in the transportation of food and organic materials in the plant.
Compare and contrast the following:
It mostly contains living cells. Transportation in the xylem is unidirectional from roots to leaves. However whereas in xylem vessels differences in pressure are produced by a water potential gradient, requiring no energy input from the plant, however in phloem transport this is not so and the plant has to use energy to create the pressure differences required for mass flow. They live with cytoplasm without the nucleus. The team of Vedantu believes in providing the best educational services to guide students and help them to excel in their classes. You stumble across a paper by Chowell et al. Sieve elements, phloem fibers, and phloem parenchyma cells are the three types of cells that make up phloem.
Compare and contrast Xylem and phloem
Forms vascular bundles with xylem. Transportation in phloem is bidirectional from leaves to various plant parts. In phloem, the conducting cells are living. The differences between xylem and phloem are as follows- Xylem is known as the permanent and dead tissue which tends to carry both water and essential substances inside the plant. Xylem The cells of the xylem tend to form long tubes that function to transport the materials. This type of flow carries from shoot to root and vice versa.
Difference Between Xylem And Phloem
High The phloem structure consists of different components like sieve tubes, sieve cells, parenchyma, sclerenchyma, and companion cells. Thus, we can guess the importance of water transport in the plant from this. Also, this type of movement occurs in the leaves to the other parts of the plant. The term xylem and phloem were introduced in 1858 by Carl Nägeli. They are made up of specialized tissues such as the xylem and phloem.
