Meristematic tissue is the dividing tissue present at the growing regions of the plants. They are meant for growth of an organ Cells of meristems divide continuously and help in increasing the length and girth of the plant
The cells of this tissue are similar in structure and have thin cellulose cell walls
The cells do not contain any intercellular space between them
The cells contain few vacuoles or no vacuoles at all
They are further divided in the following parts
1)Apical meristem
2)Lateral meristem
3)Intercalary meristem
