In monocot stems, secondary growth cannot occur, because vascular bundles are
Secondary growth refers to the growth that results from cell division in the cambia or lateral meristems and that causes the stems and roots to thicken, while primary growth is growth that occurs as a result of cell division at the tips of stems and roots, causing them to elongate and gives rise to primary tissue.
In monocot stem vascular bundles are closed, because cambia is absent. So, secondary growth can not occur
So, the correct answer is ' Closed'
