Answer
Total floral organs: 27; Average per whorl: 6.75

The correct answer is Total floral organs: 27; Average per whorl: 6.75 — Divide total organs by number of whorls: 27 ÷ 4 = 6.75.

Step-by-step solution

  1. Add all organs: 6 + 8 + 12 + 1 = 27.
  2. Count the whorls: 4 (sepals, petals, stamens, pistil).
  3. Divide total organs by number of whorls: 27 ÷ 4 = 6.75.
Common mistake: forgetting to include the pistil in the total

Concept tested: organ count and averaging
