The ultimate temptation of plants - nectar
Are you curious about the small experience of the ultimate temptation of plants - nectar? The nectar of plants is secreted to attract insects for pollination. They secrete nectar of specific flavors and colors for particular types of insects, thus evolving unique characteristics.
The flowers of plants spread pollen through various means, such as wind-pollinated flowers, insect-pollinated flowers, and water-pollinated flowers. Insect-pollinated flowers have more varied methods; some have bright appearances, some have special odors, and of course, the ultimate temptation is nectar. Nectar is a sweet and sticky juice secreted by glands called nectaries, which can attract a variety of pollinators. Nectar serves as a reward for pollinators, with sugars like sucrose, glucose, and fructose as its main components, as well as a small amount of amino acids and other substances. The nectar secreted by different flowers varies in type, volume, and color to cater to the tastes of pollinators.
The most common location for nectaries on a flower is the base of the ovary, the base of the stamens, and the base of the petals. All these positions require pollinators to pass through the reproductive organs of the flower to obtain nectar, which can promote pollination. However, the nectar-secreting glands may also grow in other parts of the ovary, such as the anthers, the stigma, and the petals.
Most nectar is colorless and attracts pollinators through its scent. However, there are exceptions, such as the blue flowers of the Chinese bellflower, which secretes scarlet sap from its blood-red nectaries to increase the chances of pollination. Its pollinators are small geckos, and the color red is highly attractive to them.
