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.
