Where does the gynoecium lie?

Think it through first, then pick an option.

  1. a Outside the petals
  2. b At the centre of the flower
  3. c Below the sepals
  4. d Beside the stamens
Answer and explanation

Correct answer: b At the centre of the flower

The gynoecium (carpel whorl) lies at the centre of the flower.

Why the other options are wrong

  • a Outside the petals: It is the calyx that lies outside the petals; the gynoecium is innermost.
  • c Below the sepals: Below the sepals lies the thalamus, not the gynoecium.
  • d Beside the stamens: Being beside the stamens does not describe its position; the gynoecium sits in the middle of all the whorls.
