what parts are responsible for fertilization in plants?

In plants, fertilization primarily involves the ovule and pollen. The male gametes, contained in pollen grains, are transferred to the stigma of the female flower, where they germinate and grow a pollen tube. This tube delivers the sperm cells to the ovule, leading to fertilization, which results in the formation of seeds. The ovary then develops into a fruit, protecting the seeds until they are ready for dispersal.
