Where do vascular tissues in non woody plants come from?

In non-woody plants, vascular tissues originate from the meristematic tissues, specifically the vascular cambium and procambium. These meristems are regions of actively dividing cells that differentiate into xylem and phloem, the two main components of vascular tissues. In herbaceous plants, these tissues are typically less complex and do not develop secondary growth, as seen in woody plants. Thus, the vascular system in non-woody plants primarily supports transport and structural integrity without extensive lignification.
