\tMeristematic Tissue:Meristematic tissues are growth tissues and found in the growing regions of the plant. According to their position in plant, meristems are apical, lateral and intercalary.\tApical meristem – Apical meristem is present at the growing tips of stems and roots and increases the length of the stem and the root.\tLateral meristem – Lateral meristems are found beneath the bark. The girth of the stem or root increases due to lateral meristem (cambium).\tIntercalary meristem – Intercalary meristem is the meristem at the base of the leaves or internodes (on either side of the node) on twigs. It increases the length of the organs such as leaves and internodes.Characteristics of Meristematic Tissues:\tTheir cells are similar in structure and have thin cellulose cell walls.\tThe cells are active and have dense cytoplasm.\tThey contain few vacuoles or no vacuoles at all.\tThe meristematic cells are compactly arranged and do not contain any intercellular space between them.
