Apical meristems contain meristematic tissue located at the tips of stems and roots, which enable a plant to extend in length. The meristem is a type of tissue found in plants. Types of Meristematic Tissue Types of Meristem Tissue: Depending upon their origin, meristems are of two types, primary and secondary. These cells are produced by primary meristematic cells that are located in the shoot apices and plant roots. Figure 16.1.1.1 Types of plant tissues. Meristematic Tissue What are meristems? Tips of Root and stem and causes increase in their length. Each type of tissue consists of different types of cells, has different functions, and is located in different places. Unlike the previous types of cells, secondary meristematic cells are produced once the plant has already started developing. Lateral meristems facilitate growth in thickness or girth in a maturing plant. The cells are small, thin-walled, with no central vacuole and no specialized features. Ø The primary function of meristem is to assist in plant growth. Primary Meristems: They are those meristematic tissues which are … Meristematic. The meristematic cells are parent ceils from which all other types of cells are formed. The meristematic tissues heal the injuries of an injured plant. 2. Intercalary Meristem:- They are present at the base of the leaves or internodes of the twigs. Lawn grasses and other monocots have an intercalary meristem, which is a region of meristematic tissue at the base of the leaf blade. Tissue Cell Types Function Locations Vascular tissue Xylem is made up of vessels and tracheids Phloem is made up of sieve cells and companion cells […] They exhibit a very high metabolic activity. They possess a single, large and prominent nucleus. The protoplasm of the cells is very dense. Specialtissue can be broadlyclassifiedinto external secretoryandinternal secretory.It is actually apermanent tissue. The group of plant cells or tissue which is in the active state of division is called meristematic tissue … Some of these cells, known as initials, maintain the meristem as a continuing source of new cells and may undergo mitosis (cell division) many times before differentiating into the specific cells required for that region of the plant body. Meristematic cells are typically small and nearly spherical. Ø They are rapidly dividing cells found in the growing portions of the plant and they give rise various plant organs. Differentiated plant cells generally cannot divide or produce cells of a different type. Meristematic tissues consist of three types, based on their location in the plant. Ø Meristem is a type plant tissue composed of an undifferentiated mass of cells. 6. Your answer : Meristematic Tissue Group of living cells which are present at specific locations and keep on dividing to add new cells in the body. It consists of undifferentiated cells (meristematic cells) capable of cell division.Cells in the meristem can develop into all the other tissues and organs that occur in plants. Meristematic tissue is located in. Plant tissues come in several forms: vascular, epidermal, ground, and meristematic. Types of meristematic tissues:- Apical Meristem:- It is present in the growing parts of the plant i.e. Permanent tissue can besimpleor complex. Explain how this type of meristematic tissue is beneficial in lawn grasses that are mowed each week. They have a dense cytoplasm and relatively few small vacuoles (watery saclike enclosures). the apical meristems at the growing points of roots and stems. 1. The main function of meristematic tissue is mitosis. The meristematic tissues are living and thin-walled. These cells do not store food. 3.
