Secondary growth usually does not occur in
Stems of monocots do not have lateral or secondary cambium. Roots of both monocots and dicots do not have secondary or lateral cambium. Hence, true secondary growth does not occur in stems and roots of monocots. But, in some exceptional cases if secondary growth takes place due to dedifferentiation of tissue cells of the cortex, pericycle etc into meristematic tissue this type of secondary growth is called anomalous secondary growth.
So, the correct answer is 'Stems and roots of monocots'
