Plant Tissue TISSUES Introduction A group of cells that are similar in structure and work together to accomplish a particular function is known as tissue. Tissues are categorized as: Plant tissue & Animal tissue Plant Tissue Following are the major types of plant tissue: Meristematic Tissues Permanent Tissues Simple Permanent tissues Parenchyma Collenchyma Sclerenchyma Epidermis Complex Permanent Tissue Xylem Phloem Meristematic Tissue Meristematic tissue mainly consists of actively dividing cells, and helps in increasing the length and thickening the stems of the plant. Meristematic tissue, commonly, present in the primary growth regions of a plant, for example, in the tips of stems or roots. Depending on the region (where the meristematic tissues are found); meristematic tissues are classified as apical, lateral, and intercalary (see the image given below). Apical meristem (as shown in the above image) is present at the growing tips of stems and roots and helps in their growth. L...
