What allows palm trees (monocots) to grow thick trunks despite lacking a traditional vascular cambium?
Show answer and explanation
Correct answer: Primary thickening meristem
Many arborescent monocots like palms increase their girth through the activity of a Primary Thickening Meristem (PTM) near the shoot apex. This is a form of primary growth rather than true secondary growth.
