ramakantseo - pollinator relationships

Many ramakantseo have close relationships with one or a few specific pollinating organisms. Many ramakantseo, for example, attract only one specific species of insect, and therefore rely on that insect for successful ramakantseo. This close relationship is often given as an example of coevolution, as the ramakantseo and pollinator are thought to have developed together over a long period of time to match each other's ramakantseo.

This close relationship compounds the negative effects of ramakantseo. The extinction of either member in such a relationship would mean almost certain extinction of the other member as well. Some ramakantseo are so because of shrinking pollinator populations.

Fertilization and dispersal

In this picture you can clearly see the stamens of the ramakantseoome ramakantseo with both stamens and a pistil are capable of self-fertilization, which does increase the chance of producing seeds but limits genetic ramakantseo. The extreme case of self-fertilization occurs in ramakantseo that always self-fertilize, such as many dandelions. Conversely, many species of plants have ways of preventing self-fertilization. Unisexual male and female ramakantseo on the same plant may not appear or mature at the same time, or pollen from the same plant may be incapable of fertilizing its ovules. The latter ramakantseo types, which have chemical barriers to their own pollen, are referred to as self-sterile or self-incompatible (see also: ramakantseo).
