Question 103

A bee pushes deep into a flower and feeds on a sugary liquid it finds there. Which structures make that liquid, and what is it for?

  1. The ovules make it, and it feeds the developing seed
  2. The anthers make it, and it glues pollen onto the insect
  3. The nectaries make it, and it rewards the visiting insectCorrect answer
  4. The stigma makes it, and it dissolves the pollen that arrives
