Answer: Simple leaves have a single, undivided lamina.
- A Simple leaves have many more leaflets per node
- B Simple leaves have a single, undivided lamina
- C Simple leaves show very little visible venation across the blade
- D Simple leaves fall off much faster each season
Correct answer: B. Simple leaves have a single, undivided lamina
Explanation: A simple leaf has a single, undivided leaf blade (lamina). A compound leaf has the blade divided into leaflets. Examples: simple - mango, banyan; compound - rose, neem, pea.
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).
