  2. Two separate pollen grains fertilize two different flowers
  3. Two ovules develop into two fruits without fertilization
  4. One sperm fertilizes two separate eggs inside a single cone
Show answer and explanation

Correct answer: A sperm fertilizes the egg; another fuses with polar nuclei

Double fertilization involves two fusion events. One sperm fuses with the egg to form the zygote, while the other fuses with the polar nuclei to form endosperm.
