What is plant xylem?
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 is a phloem easy definition?
phloem, also called bast, tissues in plants that conduct foods made in the leaves to all other parts of the plant. Phloem is composed of various specialized cells called sieve tubes, companion cells, phloem fibres, and phloem parenchyma cells. The other cell types in the phloem may be converted to fibres.
What is xylem Class 9 CBSE?
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).
What are 3 differences between xylem and phloem?
Xylem tissues are found in leaves, roots, and stems. Phloem tissues are found in stems and leaves which later grow in the roots, fruits, and seeds. Xylem tissue is composed of xylem vessels, fibers, and tracheids. Phloem tissue is composed of like sieve tubes, companion cells, phloem fibers, and phloem parenchyma.
What does a phloem do?
The phloem carries food downward from the leaves to the roots. Xylem cells constitute the major part of a mature woody stem or root. They are stacked end to end in the center of the plant, forming a vertical column that conducts water and minerals absorbed by the roots upward through the stem to the leaves.
What is difference between phloem and xylem?
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 xylem Class 10 CBSE?
Xylem transports water and minerals obtained from the soil. Phloem transports products of photosynthesis from the leaves to other parts of the plant. Vessels, tracheids of the roots, stems and leaves are connected to form a continuous system in xylem cells to transport water to all the parts of the plants.
What is xylem answer?
Xylem is a type of tissue in vascular plants that transports water and some nutrients from the roots to the leaves. The main function of the xylem is to transport water and some soluble nutrients, including minerals and inorganic ions, upwards from the roots to the rest of the plant.
What is xylem tissue class 10?
Xylem is a conducting tissue in plants. It transports water and minerals, which are absorbed from the soil by the roots of the plants, to various parts of the plant such as stems, leaves, and flowers. The two kinds of cells in xylem tissue are xylem vessels and tracheids. Both of these cells are dead cells.
Where is the xylem located?
Xylem is located in roots, stems and leaves of the plant and it transports water and minerals from plant roots to aerial parts. With phloem it forms vascular bundles. Dead cells in Xylem contribute to wooden parts of the plant.
How does xylem help move water through a plant?
The xylem helps in the movement of water from the root to the leaves. Two types of cells in the xylem, tracheids and vessels, form tubes that allow water to move up the plant. Tracheids are found in all vascular plants, but vessels are only found in flowering plants.
How do the xylem and phloem relate to photosynthesis?
Xylem tubes conduct water and minerals, while phloem tubes conduct food. Photosynthesis is the source of the energy needed to do this. It requires CO2 and water, which are carried throughout the plant by the xylem. Sugars that have been manufactured by photosynthesis are moved through the phloem cells.
What is xylem responsible for?
The xylem is the vascular tissue responsible for the upward conduction of water and nutrients from the roots. The xylem tissue moves water and nutrients to various parts of the plant such as shoots and leaves. Its major components include xylem parenchyma, xylem fibers, tracheids, and xylem vessels.
What are the features of xylem?
Centrarch: xylem forms one chamber in the middle of the stem,with metaxylem surrounding the protoxylem.
