Answer: floral diagram.
- A floral diagram
- B floral formula
- C floral chart
- D floral map
Correct answer: A. floral diagram
Explanation: A floral diagram is the pictorial representation of a flower (concentric circles for the whorls). The floral formula, by contrast, represents the same information symbolically using letters and symbols.
In a dicot stem, vascular bundles are arranged in a single ring (with cambium between xylem and phloem, enabling secondary growth); in a monocot stem, bundles are scattered throughout with no cambium, so monocots can't undergo secondary growth (no wood formation).
