| Meristematic Tissues (Meristems) |
 |
| These are composed of cells that are dividing continuously |
| |
The cells are spherical, oval, polygonal or rectangular. |
| |
The cell wall is thin and made up of cellulose. |
| |
The cells are closely arranged without inter-cellular spaces. |
| |
Cytoplasm is abundant and nuclei are large. |
| |
Vacuoles are absent and if present, very few. |
| |
Found in growing tips of root and shoot. |
| |
Found in the vascular cambium of dicot trees just beneath the bark. They are responsible for the increase in diameter of the stem. |
| |
| The main function of meristematic tissue is to continuously form a number of new cells and help in growth. |
