Answer: Anther of the stamen.
- A Pistil, the female reproductive structure
- B Ovary, where ovules later develop into seeds
- C Anther of the stamen
- D Petal, the colorful part attracting pollinators
Correct answer: C. Anther of the stamen
Explanation: Pollen grains (male gametophytes) are produced in the anthers of stamens. They contain the male gametes (sperm cells).
Double fertilisation in angiosperms: one male gamete fuses with the egg to form the diploid zygote (syngamy), while the second fuses with the two polar nuclei to form the triploid primary endosperm nucleus (triple fusion). Image: Triploid, CC BY 3.0, via Wikimedia Commons.
