Pollen tube guidance is a critical process in plant reproduction, whereby the pollen tube grows directionally to deliver sperm cells to the ovule for fertilization. This intricate journey involves chemical signals emitted by the female reproductive tissues that navigate the pollen tube to its final destination, ensuring successful fertilization and seed development.
Plant fertilization is the process by which male and female gametes unite, resulting in the formation of a zygote and eventually leading to seed development. This process is crucial for sexual reproduction in plants, enabling genetic diversity and adaptation in various environmental conditions.
