Diurnality - in Plants

In Plants

Many plants are also diurnal or nocturnal, depending on the time period when the most effective pollinators, i.e., insects, visit the plant. For example, as most angiosperm species of flower are visited by many various insects, the flower adapts its phenology to the most effective pollinators in order to ensure proper reproduction and longevity of the species. Thus, the effectiveness of relative diurnal or nocturnal species of insects affects the diurnal or nocturnal nature of the plants they pollinate, causing in some instances an adjustment of the opening and closing cycles of the plants.
