Which of the following correctly explains the intercalary meristem and its role in plant growth?
| 1. | A meristematic tissue located at the apex of the root, responsible for the elongation of primary roots. |
| 2. | A meristematic tissue occurring between mature tissues, contributing to the regeneration of parts removed by grazing herbivores, particularly in grasses. |
| 3. | A secondary meristematic tissue responsible for producing cork and secondary vascular tissues in woody plants. |
| 4. | A permanent tissue forming the protective covering of leaves and stems, minimizing water loss. |

4. All statements except I
| Statement I: | Intercalary meristems are located between mature tissues and contribute to the regeneration of organs in grasses. |
| Statement II: | Both apical and intercalary meristems are categorized as primary meristems as they originate early in the plant's life. |
