Solution
Once the pollen reaches the stigma, the pollen tube traverses down the style to the ovary where fertilization occurs.
Explanation:
Once the pollen reaches the stigma, it grows a tube called the pollen tube, which travels down the style. The style is a narrow, tube-like structure that connects the stigma to the ovary. The pollen tube continues down the style until it reaches the ovary, where it releases the sperm cells to fertilize the ovule. This fertilization process leads to the development of seeds.
