If conditions are not suitable for natural pollination, hand pollination, also known as manual or mechanical pollination, must be performed. This can be something of a lottery; after all, once the pollen is carried aloft on the breeze, the plant has no control over where it will land.

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 an excellent example of a dioecious tree because it produces both male and female trees. [3] It is a member of the genus Phleum, consisting of about 15 species of annual and perennial grasses.
