Question

In flowering plants, double fertilization is a distinctive process. What are the two main fusions that occur during this event?
Options
A One sperm + egg, and a second sperm + polar nuclei
Correct Answer
B Egg + pollen, and zygote + endosperm
C Ovule + ovary, and stamen + pistil
D Radicle + plumule, and seed + fruit
Correct Answer

Option A is the correct answer.

Detailed Explanation

Double fertilization involves two distinct fusions: one sperm fuses with the egg nucleus to form the diploid zygote, and a second sperm fuses with the polar nuclei to form the triploid endosperm. This process is unique to flowering plants.

Hint

Recall the specific products formed by the two sperm cells after entering the ovule.
