How does the structure of xylem and phloem relate to their function?
Xylem transports and stores water and water-soluble nutrients in vascular plants. Phloem is responsible for transporting sugars, proteins, and other organic molecules in plants. Vascular plants are able to grow higher than other plants due to the rigidity of xylem cells, which support the plant.
What is the structure of xylem?
Xylem is made up of tracheids, vessel, xylem parenchyma and xylem sclerenchyma. Tracheids and vessels collectively called the tracheary elements. These are conducting cells of xylem. The vessels are found only in angiosperms and advanced gymnosperms.
How does the xylem structure facilitated transport?
The water-conducting xylem cells provide an internal hydrophobic surface facilitating water transport as well as mechanical strength. The xylem cells also support the weight of the water transported upward in the plant and the weight of the plant itself.
What is the function of xylem and its 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 |
How does the structure of phloem relate to its function?
The cells that make up the phloem are adapted to their function: Each sieve tube has a perforated end so its cytoplasm connects one cell to the next. Companion cells – transport of substances in the phloem requires energy. One or more companion cells attached to each sieve tube provide this energy.
What is the function of xylem in science?
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.
How the xylem is different from the phloem?
Xylem is the complex tissue of plants, responsible for transporting water and other nutrients to the plants. Phloem is living tissue, responsible for transporting food and other organic materials.
What are two kind of xylem and their functions?
Primary xylem and secondary xylem are two growth stages of the xylem in angiosperms and some gymnosperms. The main function of the xylem tissue in plants is to conduct water and minerals from root to the leaf.
What are two functions of the xylem cells?
Xylem Definition. Xylem is a type of tissue in vascular plants that transports water and some nutrients from the roots to the leaves.
What is the main function of xylem and the 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.
What is the function of the xylem vessels?
The xylem vessel is specialised to transport water and dissolved minerals from the root up to all the other parts of the plant, and also to helps supporting the stem and strengthening it. This is a long tube that runs alongside the xylem tissue.
