Nectar
Nectar
Nectar (/ˈnɛktər/), from the Greek word νέκταρ (néktar), is a sugar-rich liquid produced by plants, particularly within flowers. It serves a crucial role in the foraging economics and overall evolution of pollinator species, such as bees and hummingbirds.
Etymology
The term "nectar" is derived from the ancient Greek word νέκταρ (néktar), which was the drink of the gods in Greek mythology. It was said to confer immortality upon any mortal who consumed it.
Production and Function
Nectar is produced by glands known as nectaries. Most commonly, these are found within the flowers of plants, but they can also be found on other parts of the plant, such as the leaves, stem, or bark. The primary function of nectar is to attract pollinators to the plant, encouraging them to visit multiple flowers and thus facilitate pollination.
Composition
Nectar is primarily composed of water and sugars, such as sucrose, fructose, and glucose. It may also contain small amounts of proteins, salts, acids, and essential oils. The exact composition can vary depending on the species of plant and environmental conditions.
