Question
what is a pollen tube
Answers
GPT-4o mini
A pollen tube is a structure that forms during the process of plant fertilization. When pollen grains land on a compatible stigma (the receptive part of a flower's ovary), they germinate and produce a pollen tube. This tube is an elongated structure that grows down through the style, which connects the stigma to the ovary, and into the ovule.
The primary purpose of the pollen tube is to transport sperm cells from the pollen grain to the ovule, where fertilization occurs. This can lead to the formation of seeds and, ultimately, the development of a new plant. The successful growth of the pollen tube is crucial for sexual reproduction in flowering plants (angiosperms).
