Question 99

What exactly is pollination?

  1. The joining of a pollen nucleus with an ovule nucleus
  2. The transfer of pollen from an anther to a stigmaBonne réponse
  3. The growth of a pollen tube down through the style
  4. The ripening of the ovary into a fruit

Explication

Pollination is a journey and nothing more: pollen leaves the male part and arrives on the receiving surface of a female part, and the event is finished at the moment it lands. The union of nuclei is a later and separate step that can only follow arrival, so treating the two as one collapses a sequence of events into a single word.
