Look closely at the trout-lily on the left and you will notice a small insect brushing against the pollen on the anthers of the flower. As the insect moves, it transfers the pollen to the stigma thereby fertilizing the seeds that will ripen to germinate and produce another generation of trout-lilies.

Beautiful carpenter bee on an Atlantic Camas wildflower. I love their eyes. Found out the white on the face makes it a male.

In angiosperms, after the pollen grain (gametophyte) has landed on the stigma, it germinates and develops a pollen tube which grows down the style until it reaches an ovary. Its two gametes travel down the tube to where the gametophyte(s) containing the female gametes are held within the carpel. After entering an ovum cell through the micropyle, one male nucleus fuses with the polar bodies to produce the endosperm tissues, while the other fuses with the ovule to produce the embryo. Hence the term: "double fertilization". This process would result in the production of a seed made of both nutritious tissues and embryo.
In gymnosperms, the ovule is not contained in a carpel, but exposed on the surface of a dedicated support organ, such as the scale of a cone, so that the penetration of carpel tissue is unnecessary. Details of the process vary according to the division of gymnosperms in question. Two main modes of fertilization are found in gymnosperms. Cycads and Ginkgo have motile sperm that swim directly to the egg inside the ovule, whereas conifers and gnetophytes have sperm that are unable to swim but are conveyed to the egg along a pollen tube.
The study of pollination spans many disciplines, such as botany, horticulture, entomology, and ecology. The pollination process as an interaction between flower and pollen vector was first addressed in the 18th century by Christian Konrad Sprengel. It is important in horticulture and agriculture, because fruiting is dependent on fertilization: the result of pollination. The study of pollination by insects is known as anthecology. There are also studies in economics that look at the positive and negative benefits of pollination, focused on bees, and how the process affects the pollinators themselves.
