Based on the location, Meristematic tissues can be classified as: 1. The figure given below, depicts the types of plant tissues. In some plants dedifferentiation occurs at definite regions at certain stages of development to supplement the conducting and protective tissue system. The vascular tissues are of two kinds: water-transporting xylem and food-transporting phloem. Also the next classification of plants is also known as the tracheophytes, vascular plants have been allowed by evolution to possess vascular tissues (xylem and phloem) that aid them to transport water and minerals. As a result of improved organization and higher efficiency, multicellular organisms have higher survival. The tissues of this system are meant for gaseous exchange between internal tissues and external atmosphere. All the tissues of a plant which perform the same general function, regardless of position or continuity in the body, constitute the tissue system. Answered Classification of plant tissue 2 Also Read: Plant Tissue System. Depending upon this criteria plants are classified as vascular (having xylem and phloem) and non-vascular (not having xylem and phloem). Plant tissue systems fall into one of two general types: meristematic tissue and permanent (or non-meristematic) tissue. I. TOS4.

Primary dermal tissues, called epidermis, make up the outer layer of all plant organs (e.g., stems, roots, leaves, flowers). Parenchyma tissues are found in the soft parts of plant such the roots, stems, leaves and flowers. What are the functions of the nervous system? Tracheids and Vessels I) Embryo Culture: For embryo culture, embryos are excised from immature seeds, usually under a ‘hood’, which provides a clean aseptic and sterile area. Animal tissues can be grouped into four basic types: epithelial, muscular, connective and nervous tissues. Welcome to BiologyDiscussion! Log in. The meristematic tissue cells have the ability of dividing and they are situated in the root apex and stem apex. A tissue is a cluster of cells, that are alike in configuration and work together to attain a specific function. Plant tissues are either simple (composed of similar cell types) or complex (composed of different cell types). Dermal tissue; Vascular tissue; Ground tissue; Meristematic tissue; Medical histology. Function. What is Dermal Tissue System? Most of the plants release many substances from their cell cytoplasm to the exterior and they are called as Plant-secretions. Related Videos. Each type of tissue consists of different types of cells, has different functions, and is located in different places. Plants that have vascular tissues for the transport of food and water are commonly known as tracheophytes. Plant tissues may be divided into three types: Meristematic tissues; Permanent tissues; Secretory tissues; Meristematic tissues: Meristematic tissue includes group or cluster of cells which remain in continuous state of division or retain their power of division. Dermal tissue is composed of epidermis and periderm. They assist in the major growth of the vegetation.
