Which of the following is NOT a component of a flower?

Question

Accepted Answer

Step-by-step explanation:

1. Identify the listed items:
   - Androecium = the male reproductive whorl (stamens) of a flower.
   - Corolla = the collective term for petals.
   - Calyx = the collective term for sepals.
   - Spines = sharp outgrowths, typically from stems or leaves, not a floral whorl.

2. Recognize standard floral components: sepals (calyx), petals (corolla), stamens (androecium), and pistil/gynoecium are the main parts of a flower.

3. Conclusion: "Spines" are not a component of a flower but are vegetative or defensive structures; therefore option (3) is NOT a component.
