Answer: A small bulb-like structure that functions as a vegetative propagule (asexual reproduction).
- A A type of fleshy, starch-storing underground root, similar in form to a sweet potato
- B A small bulb-like structure that functions as a vegetative propagule (asexual reproduction)
- C A modified leaf-like floral bract that surrounds and protects the developing flower bud
- D A small leaf-like stipule appendage attached firmly at the base of the leaf petiole
Correct answer: B. A small bulb-like structure that functions as a vegetative propagule (asexual reproduction)
Explanation: Bulbils are small, fleshy, vegetative buds that fall from the parent plant and germinate to form new individuals. Found in Agave (leaf bulbils), Oxalis (stem bulbils), and some lilies. They represent vegetative propagation.
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).
