Required fields are marked *. PERMANENT TISSUE. These cells divide and form permanent tissues. Classification on basis of plane of divisions: The growth pattern and plane of division of meristematic tissue is important to govern the mode of growth. Share Your PPT File. The meristematic tissues divide to form new cells which differentiate to give rise to permanent tissues. It can be observed in meristems of cortex and pith. These are present at the tips of the roots and shoots and helps in the increase of the height of the plants. Meristematic Tissue – Based on Occurrence. It arises from the promeristem. Several theories have been put forward to explain the activity of apical meristem: The theory was first proposed by Hofmeister (1857) and advanced by Nageli (1878). The primary meristem arises from the promeristem. Meristems and Simple Plant Growth. It is present below the promeristem and forms the permanent tissue. The meristematic tissue has the quality of self-renewal. No need to register, buy now! Intercalary meristem 3. These are found at the apices or growing points of root and shoot and bring about increase in length. The basic function of these cells is that they have the ability to continuously divide, producing newer cells similar to them. vascular, dermal or ground tissue). Meristem is undifferentiated plant tissue found in areas of plant growth. The protoplasm of the cells is very dense. There are three main types of meristems that plants have: apical, lateral and intercalary. The cells of the meristematic tissue are young and immature. for eg :- root tip,shoot tip and the cambium..they are responsible for the increase in the length as well as girth (thickness) of the plant..meristematic tissues are mainly of three types:- They possess a single, large and prominent nucleus. (v) They do not store reserve food material and are in an active state of metabolism. Disclaimer Copyright, Share Your Knowledge Types of meristematic tissue are apical meristem, Intercalary meristem, lateral meristem. The cells of the meristematic tissue divide actively to form specialized structures such as buds of leaves and flowers, tips of roots and shoots, etc. hypodermis, cortex and pith. Meristematic Cell: Notes on Meristematic Cell | Botany, Essay on the Classification of Meristems | Plant Tissues | Botany, 3 Types of Permanent Tissues and their Functions. What are the main function of meristimatic tissue, Your email address will not be published. Primary Meristem. This division helps in the increase of parts of plants in girth and length. Classification based on origin and development: On the basis of origin and development of initiating cells, meristems can be divided into three types: A group of young meristematic cells of a growing organ. The meristematic tissue is of the following types: Meristematic Tissue On the basis of Origin Promeristem. Term meristem suggested by Nageli, 1858. Collections of tissues joined in units to serve a common function compose organs. (With Methods)| Industrial Microbiology, How is Cheese Made Step by Step: Principles, Production and Process, Enzyme Production and Purification: Extraction & Separation Methods | Industrial Microbiology, Fermentation of Olives: Process, Control, Problems, Abnormalities and Developments, The best answers are voted up and rise to the top. Meristematic Tissue. Apical meristemis present on root and shoot tips of the plant. Apical meristematic tissue is found in buds and growing tips of plants. They possess a single, large and prominent nucleus. Types of Meristematic Tissue. It is found in grass, monocots and pines. Carl Wilhelm von Nägeli coined the term “meristem.” Meristematic tissue contains undifferentiated cells, which are the building blocks of the specialized plant structures.
