A pollen grain is a male haploid gametophyte that has evolved to be delivered to a female gametophyte. In a process known as double fertilization, it can fertilize the female gametophyte by creating the male gamete (or gametes). The pollen travels through the pollen tube.

Ovules form into seeds following the fertilization of an ovum. The ovary matures into a fruit, and the ovules develop into seeds. The integument wraps the ovule, and the nucellus, which contains the embryo sac and provides nourishment, is the most significant component.

Style is a component of the plant's female reproductive system. A flower's style is a structure within the blossom. The stigma and the ovary are connected by a long, thin stalk that is style. The plant's ovules are housed in the ovary, found at the bottom of the style.

The ovule is a long, thin stalk that connects the ovary and stigma. A style is a type of internal structure seen in flowers. A shorter style does not rule out pollen grains that are incapable of functioning correctly.
