Answer
The types of plants most likely to have a vascular cambium are woody dicots and gymnosperms. Here’s a breakdown:
1. Woody Dicots (Angiosperms)
- Examples: Oaks, maples, and magnolias.
- Vascular Cambium Presence: Woody dicots have a well-developed vascular cambium that contributes to secondary growth. This growth is responsible for the formation of annual growth rings and the thickening of stems and roots.
2. Gymnosperms
- Examples: Pines, spruces, and firs.
- Vascular Cambium Presence: Gymnosperms also have a vascular cambium that facilitates secondary growth. Similar to woody dicots, the vascular cambium in gymnosperms produces secondary xylem (wood) and secondary phloem, contributing to the increase in trunk and root diameter.
Less Likely:
- Monocots: Plants such as grasses and lilies do not have a vascular cambium. Instead, they undergo primary growth, which increases the length of stems and roots but not their girth. Monocots generally lack secondary growth and do not form true wood or bark.
