Nurturing Bumblebees

Expert details on what makes magnificent bumblebees the perfect pollinators.

Like palace guards, the stamens stand in a circle around the pistil (with ovary within) forming a tube-like structure with an opening only at the exposed end. The pollen is firmly attached inside the anthers, capping the stamens. Something has to shake the stamens to release the pollen through pores in the anthers.
