The tips of the stem and roots are occupied by

  1. Secondary Meristem

  2. Apical Meristem

  3. Primary Meristem

  4. Intercalary Meristem


Correct Option: C
Explanation:

It is the meristem, that is present right from the embryonic stage, and continues to be active, throughout the life of a plant. It is responsible for primary growth, in the plant body. It gives rise, to the primary permanent tissues, of the plant body. Example: Meristem found at the tip of the stem and root.
