On the surface of the water, pollen travels in two dimensions, rather than three, which is advantageous. Non-flowering plants, such as conifers, fern, and moss, are not immune to insect or animal interactions. It carries the trees male genes; it is the male fertilizing unit of woody plant reproduction. Bright and colorful plants often are insect-pollinated, producing pollens that are larger, heavier and stickier.

Pollen grains are produced in large numbers by the anthers, whereas stamens protrude out of the flowers and are generally long and erect. Even more venerable than the angiosperms are the gymnosperms. The female parts are called carpels. In flowers that are pollinated by the wind, the pollen grains that are produced are smaller and lighter in weight, making them easier to transport by the wind. They produce pollen that is light and released in large quantities that can be easily inhaled. In flowers, the male reproductive organs are referred to as stamens. Wind-borne pollinating plants, including trees, grasses and weeds, are most likely to cause a seasonal allergic reaction. They are typically brightly colored to attract insects, but many lack the ability to produce their own honey. Wind pollination is most effective in open habitats and in early successional ecosystems, where wind is likely to be an advantage. The interactions between insect pollinators and flowers are a good example of what is known as a symbiotic relationship, in which the lives of two organisms are intimately intertwined. Aspen (Populus tremula) is a notable example of a dioecious tree. As many as 40 million people have hay fever (allergic rhinitis), which can cause symptoms such as sneezing, runny nose, itchy, watery eyes, wheezing and cough.

Unlike the angiosperms, these plants dont have ovary-encased seeds, but rather pollen-producing cones. This carries weighty implications for genetic variation and flexibility, which in turn allow species to cope with varied habitats and changing growing conditions over time.
