The term ‘xylem’ is derived from the Greek word ‘xylon’, meaning wood. A collection of cells performing a specific function is called tissue. Xylem and phloem are the two complex tissues which are discussed hereunder. These are usual­ly primary in nature. tissue between the dermal tissue and vascular tissue of a non-woody plant that functions in photosynthesis, storage, and support Root hair cell Cell found on the surface of plant roots that has a large surface area to absorb water and dissolved mineral salts quickly from the soil. These lacunae resemble typical air-chambers (air-spaces). Plant Structure and Function. The xylem is a tissue which transports water and minerals from the roots up the plant stem and into the leaves. Xylem is the dead, permanent tissue that carries water and minerals from roots to all other parts of the plant. Definition of Xylem. Xylem Xylem_cells. Q2. Reduction of Absorbing Tissue: Xylem and phloem together make the vascular bundle in plants. The vascular tissue system consists of the complex tissues, xylem and phloem, which constitute discrete conducting strands called vascular bundles. The endodermis is generally present around the stele, but it is weakly developed. a. The main activity of this tissue is to transport minerals and water from roots and carry them to other parts of the plants. It has two separate chambers, tracheids and vessels for transporting minerals and water. Xylem is formed by tracheary elements like tracheids and vessels predominantly. Draw a labelled diagram of xylem tissues. Xylem Tissues. In several aquatic plants, the phloem is fairly well developed as compared with the xylem. Search for: Pholem and Xylem Diagrams. Pholem Phloem_cells. Asked by Virender | 29th Jun, 2018, 10:08: PM. 1. In these plants, there is well evolved xylem lacuna in the position of xylem. Xylem: The cells have thick cell wall and many of them are dead. There are a variety of other cells giving it the status of complex tissue. Primary xylem originates from the procambium during primary growth while secondary xylem has its origin in vascular cambium during secondary growth. The elements of xylem and phloem have already been discussed in the preceding chapters. Phloem, on the other hand, is the living, permanent tissue that carries food and other organic nutrients from leaves to all other parts of the plant. This tissue helps in the transport of water and dissolved substances throughout the plant. In vascular plants, xylem is the type of transport tissue.These are dead, complicated, and permanent tissue.The substantial task is to carry water and other nutrients to different parts of the plants.. Xylem is chiefly formed of the vessels and tracheary elements like tracheids, vessels, xylem parenchyma. Xylem is one of the important tissues of the vascular system of plants. Xylem consists of dead cells. Anatomy. Most candidates were able to score the one mark for this part of the question as many alternatives were given in the markscheme. The different components of the xylem include tracheids, vessels, xylem parenchyma and xylem fibres. Xylem is the tissue which is responsible for the transport of water in plants while the phloem is responsible for the transfer of food and nutrients in the plant. Plant tissues can be grouped into plant tissue systems each performing specialized functions. The vast majority of candidates were able to correctly label this as xylem although many respondents on the G2 form indicated that they found the diagram difficult. These tissues are responsible for the conduction of substances in plants from top to bottom and thus helps in transporting materials to and from top and bottom of the plant.
