    They are located at the tips of stems and roots, and ensure that plants grow lengthwise by forming clumps of cells in a non-ordered arrangement.

  • Secondary meristems

    They appear in the plant from the second year onwards, in the form of continuous layers of cells called "assises", and ensure growth in diameter by producing cells aligned in the continuation of the meristematic cell...
