Answer: Ovule (for fertilization).
- A Petal, where it deposits the male gametes
- B Nearest leaf, absorbing nutrients along the way
- C Ovule (for fertilization)
- D Root, traveling down through the vascular tissue
Correct answer: C. Ovule (for fertilization)
Explanation: After landing on stigma, the pollen grain germinates and grows a pollen tube through the style to reach the ovule, delivering male gametes for fertilization.
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.
