Pls tell me about nectar in flowers.in detail...
Nectar is the sweet viscous secretion from the nectaries, or glands, in plant blossoms, stems, and leaves.The main ingredients in nectar are natural sugars in varying proportions of sucrose, glucose, and fructose.It attracts fruit-eating bats, hummingbirds, and insects, who aid in effecting pollination by transferring from plant to plant the pollen that clings to their bodies.While collecting the nectar, pollinators accidentally transfer pollen from male flowers to female flowers.
Nectar is the raw material used by the honey bee to produce honey. Mainly a watery solution of the sugars fructose, glucose, and sucrose, it also contains traces of proteins, salts, acids, and essential oils. Sugar content varies from 3 to 80 percent, depending upon such factors as flower species and soil and air conditions. Honeybees gather nectar mainly from the blossoms and rarely gather nectars having less than 15 percent sugar content. A voluminous floral nectary surrounds the ovary.
Nectar plays an important role in the foraging economics and overall evolution of nectar-eating species; for example, nectar and its properties are responsible for the differential evolution of the African honey bee.Nectar secretion increases as the flower is visited by pollinators. After pollination, the nectar is frequently reabsorbed into the plant.
