Describe the functions of meristematic, xylem and phloem tissue. PARALLEL Morphology of Leaf RETICULATE VENATION:-When the veins and veinlets form a network, it is called reticulate venation. Solution: (b) Xylem (a complex permanent tissue) is the chief conducting tissue of vascular plants responsible for conduction of water and inorganic solutes. In some highly specialized tree species with large vessels (such as some oaks , ashes , and others), only the very outermost growth ring functions in water conduction. It consists of a combination of parenchyma cells, fibers, vessels, tracheids, and ray cells. The parenchyma of stems and roots also stores nutrients and water. Vascular tissue is an arrangement of multiple cell types in vascular plants which allows for the transport of water, minerals, and products of photosynthesis to be transported throughout the plant. Xylem serves as a chief conducting tissue of vascular plants. It is responsible for the conduction of water and mineral ions/salt. Xylem is meant to conduct water and mineral salts upward from root to the leaf and give mechanical strength to the plant body. Plants have two systems for the transportation of substances - using two different types of transport tissue. Explanation: The vascular bundle is the system of plants regarding the conduction of food, water, and minerals. - They are concerned with the conduction of water, mineral salts and food and form the structural framework of the lamina. Water potential, evapotranspiration, and stomatal regulation influence how water and nutrients are transported in plants. The tissue that helps in the sideways conduction of water in the branches is (a) collenchyma (b) xylem parenchyma (c) parenchyma (d) xylem vessels. Xylem serves as a chief conducting tissue of vascular plants. Water movement. Rise of cell sap: The upward movement of water with dissolved minerals from roots to the tips of stem, branches and their leaves is called ascent of sap (Fig. Its function are principally to protect the plant from injury or adverse conditions and to reduce water loss. Phloem tissue is composed of sieve-tube cells, companion cells, phloem parenchyma, and phloem fibers. Xylem transports water and solutes from the roots to the leaves, while phloem transports food from the leaves to the rest of the plant. Sieve tube. Roots.

Parenchyma Tissue: The most abundant, diverse, and versatile cells in a plant are found in the parenchyma tissue. Vascular tissue definition is - plant tissue concerned mainly with conduction; especially : the specialized tissue of higher plants consisting essentially of phloem and xylem. The lighter-coloured sapwood is living and functions as storage tissue and, especially in the outermost sapwood, as conducting tissue; the younger annual rings make up the sapwood. (1979). Existing Student Sign In x. Forgot password? ... type of plant tissue specialized to conduct water and nutrients throughout a plant. In flowering plants, both xylem vessels and tracheids, or only vessels are concerned with conduction of water and minerals from roots to the aerial parts of the plant. Xylem is a specialized type of vascular tissue created in vascular plants to transport water and nutrients from the roots of a plant to the tips of the leaves. The leaves are healthy due to continuous supply of water through the xylem tissues. Explanation: The vascular bundle is the system of plants regarding the conduction of food, water, and minerals. Xylem is the tissue concerned with upward conduction of water in plants. Xylem tissue is used mostly for transporting water from roots to stems and leaves but also transports other dissolved compounds. The Tissue Concerned with Upward Conduction of Water in Plants. transfer of pollen from the male reproductive structure to the female reproductive structure. Which of the following is produced in the liver? Non-vascular plants, such as some algae and moss, do not have vascular tissue and therefore cannot easily transport water and nutrients.

As growth proceeds, the cork cambium forms in living cells of the epidermis, cortex, or, in some plants, phloem and produces a secondary protective tissue, the periderm. (e) The term for the inward movement of solvent molecules through the plasma membrane of a cell. The intensive variable is water potential, and it describes the intensity or quality of water in plant tissue or soil. The structure of plant roots, stems, and leaves facilitates the transport of water, nutrients, and photosynthates throughout the plant. Such a parenchyma type is called aerenchyma. The conducting system: Xylem and phloem compose this system and they are concerned with upward conduction of water and downward translocation of solutes. Plant water relationship. These MCQ Objectives are helpful in the revision of chapter as well as clearing the concepts also. Water will always flow from high potential to low potential. Transfer Cells: rapid transport of food metabolites associated with veins of leaves and nectaries of flowers. Xylem tissue is organised in a tube-like fashion along the main axes of stems and roots. It consists of two parts xylem, which is the water-conducting tissue, and the phloem, which is concerned with the conduction of food (glucose). Xylem vessels and tracheids are non-living plant tissues that are thick-walled while xylem parenchyma is a living tissue. The water along with dissolved minerals is absorbed by the root hairs of the roots from the soil. pulvinus. Every cell in the plant needs water and minerals to survive, and complete necessary reactions. True. Describe the functions of meristematic, xylem and phloem tissue.

View Answer. (vii) The inward movement of solvent molecules through the plasma membrane of cell. Many questions about water availability and movement are best answered by measuring soil water potential. Changes in the water content of tree tissues were measured by a number of workers in the 1950s, 1960s and 1970s, but water storage in stems (sapwood) in large trees seems to have been first identified as a significant factor in the seasonal water relations and water balance of conifers by Waring and Running (1978) and Waring et al. Freshwater algae, which are thought to be the precursor of land plants, suggest that they are one of the earliest plant cell types in the Kingdom Plantae.
