Meristematic tissue has a number of defining features, including small cells, thin cell walls, large cell nuclei, absent or small vacuoles, and no intercellular spaces. It is commonly referred to as meristem and occurs in the growing regions of the plant body. (2000) have reported at par or slightly better performance of tissue culture raised plants than mother plant in terms of their photosynthetic characteristics and morphological parameters. 1. Some cells produced by meristematic tissue stop dividing and acquire certain changes to become permanent tissues of the plant. Meristematic tissue has the ability to divide and redivide to provide growth to plants.Generally, growth of plants occurs from specific region like root and shoot, nodes, girth of stem, leaf base etc. Meristematic tissue : Meristematic tissues may be defined as a group or collection of living cells which ar located specific locations and divide continuously to add new cells to the plant body. Meristem is a group of plant cells that remain in a continuous state of division. The meristem composed of rapidly dividing undifferentiated mass of cells. Consists of small, cubodial densely packed cells with thin cell walls & large nuclei, which keeps on dividing to form new cells. Facebook Twitter LinkedIn Reddit Email Vk.com. Meristematic tissue and ground tissue are two types of tissues found in plants. Related Topic:-Define Tissue in biology Animals and plants both are multicellular organisms. They are living and thin walled. The word “Meristem” originated from “Meristos” (Greek = continuous division) and the term meristem was introduced by Nageli (1858). The group of plant cells or tissue which is in the active state of division is called meristematic tissue or meristems. A meristematic tissue (meristos = divisible) is a group of identical cells that are in a continuous state of division. Together the ground substance and fibers make up the extracellular matrix. They are compactly arranged in tissue and there is absolutely no intercellular space. They do not contain reserve food materials, ER and plastids. This change from meristematic to permanent tissue is called differentiation. Some cells produced by meristematic tissue stop dividing and acquire certain changes to become permanent tissues of the plant. 0 like .

In a similar experiment Bag et al. Connective tissue is the most abundant and widely distributed of the primary tissues. A meristematic tissue constitutes a group of actively dividing cells present in the growing region of plant, e.g., the tips of roots and stems. Most of the tissues they have are supportive, which provides them with structural strength. Q2. Almost no Vacuoles present. The cells of this tissue continusly divide and add new cells in the plants. They are compactly arranged in tissue and there is absolutely no intercellular space. The cells of this tissue have dense cytoplasm. Apical cell theory was given by Hofmeister Hanstein Haberlandt Grew Answer: 1 Q2. The cells of meristematic tissues are rich in cytoplasm. The cells of this tissue lack vacuoles. Having large nuclei. Question 1. It is known as undifferentiated tissue because cells in the meristematic tissue will eventually become vascular, ground, or dermal tissue. The main difference between meristematic tissue and ground tissue is that the cells in the meristematic tissue are capable of continuously dividing whereas ground tissue is a type of a permanent tissue whose cells are incapable of dividing. Cells have the power of active division. Source | Credits | Picture Credits: NCERT General Science Plant Tissues Plants are stationary or fixed – they don’t move. Share your questions and answers with your friends. Have cells that are tightly packed in layers or rows. Cells are very small and isodiametric. They are made up of immature cells. This tissue forms glandular structure which secrete or excrete chemical substances. 1. This change from meristematic to permanent tissue is called differentiation. They are diploid in nature and show mitotic division. 5. Types of meristematic tissue are apical meristem, Intercalary meristem, lateral meristem. A group of cells which are similar in origin; similar in structure and similar in function are called simple permanent tissue. The short answer to your question is that meristematic tissues are capable of dividing, cleaving off cells in one or another direction. Connective tissue has three main components: cells, fibers, and ground substance. They keep on dividing. Complex Permanent Tissue: Xylem, Phloem. These glands are present on the epidermis; Some plant having glandular tissue are Betel plant (mucilage), lemon , orange (oil), Sundew, Venus fly, Pitcher plant etc; Permanent tissue: characteristics, types and functions answer comment. Continuously dividing cells. The cells of the meristematic tissues are quite distinct in their cytological and physiological characteristics from other cells. Characteristics of meristematic tissues. The term meristem was proposed by Karl Nägeli from a Greek word ‘merizein’ which means ‘to divide’. Divisions characteristic of Korpe-Kappe theory are Anticlinal T-type Periclinal Irregular Answer: 2 Q3. The characteristic features of meristmatic tissue are as follows : o The cells are structurally alike and are always living as well as thin-walled. 1. Cells are generally cubical in shape. Permanent tissue: The kind of tissue in which the cells lose their dividing capacity after originating from meristematic tissue is known as permanent tissue. Meristematic tissues are cells or group of cells that have the ability to divide. These meristematic cells may be rounded, oval, polygonal or rectangular in shape. Meristematic tissues, or simply meristems, are tissues in which the cells remain forever young and divide actively throughout the life of the plant. 2.

The cell wall is thin and made up of cellulose. The growth of the plant body occurs in two steps; the new cells are produced first, and then these cells are expanded by absorbing water by the vacuole.The cell division only occurs in meristematic tissue but, the expansion can occur anywhere … The following are the characteristics of the meristematic cells. There are two types of apical meristem tissue: shoot apical meristem (SAM), which gives rise to organs like the leaves and flowers, and root apical meristem (RAM), which provides the meristematic cells for future root growth.SAM and RAM cells divide rapidly and are considered indeterminate, in that they do not possess any defined end status. ANSWER:-The cells are highly active. 3. It is formed as a result of division and differentiation of meristematic tissue. The following are the characteristics of the meristematic cells.
