The 'Siphonogamy' seen in Phanerogams refers to:

  1. Pollination by insects
  2. Reproduction by vegetative spores
  3. Fertilization requiring external water
  4. Male gamete transport via pollen tube
Show answer and explanation

Correct answer: Male gamete transport via pollen tube

Siphonogamy is the process where a pollen tube carries the non-motile male gametes to the female gamete. This adaptation allows seed plants to reproduce successfully on land without liquid water for sperm travel.
