They are made up of immature cells. * The group of young cells which have tendency to divide is called meristematic tissue. What are the characteristics of meristematic Tissues? They are living and thin walled. The meristem composed of rapidly dividing undifferentiated mass of cells. They are compactly arranged without intercellular spaces between them. These meristematic cells may be rounded, oval, polygonal or rectangular in shape. 2. It is commonly referred to as meristem and occurs in the growing regions of the plant body. The cells of meristematic tissues are rich in cytoplasm. This tissue forms glandular structure which secrete or excrete chemical substances. The cells of the meristematic tis­sues are quite distinct in their cytologi­cal and physiological characteristics from other cells. 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. 2. 4. It is a tissue system in plants called meristematic tissue. The short answer to your question is that meristematic tissues are capable of dividing, cleaving off cells in one or another direction. 3. 4) They have a dense cytoplasm with a prominent nucleus. avy002 avy002 Answer: 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. Source | Credits | Picture Credits: NCERT General Science Plant Tissues Plants are stationary or fixed – they don’t move. A meristematic tissue (meristos = divisible) is a group of identical cells that are in a continuous state of division. Characteristics of meristematic tissues : The cells of meristematic tissues are similar in structure and have thin and elastic primary cell walls made up of cellulose. 2. 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. 0 dislike.

CMCs were induced within 4 to 7 days of culturing in media … Meristematic tissue and ground tissue are two types of tissues found in plants. They are diploid in nature and show mitotic division. Therefore, meristematic tissue is present in these regions. Plant Tissue - Meristematic Tissue, Permanent Tissue - Simple Permanent Tissue: Parenchyma, Chlorenchyma. The cells of the meristematic tissues are quite distinct in their cytological and physiological characteristics from other cells. 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. Together the ground substance and fibers make up the extracellular matrix. The group of plant cells or tissue which is in the active state of division is called meristematic tissue or meristems. Nuclei are large. Characteristics of meristematic tissues: The cells of the meristematic tissue are similar in structure and have thin cellulose cell walls. Cells have the power of active division. The cells of this tissue have dense cytoplasm. 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 … Meristematic tissue. 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.
