nectar -

Nectar or flower essence is a sweet liquid rich in sugar produced by flowers from plants in bloom to attract the arrival of pollinating animals like insects. Nectar is produced by the nectar gland which usually lies at the base of flower jewelry (perianthium), so pollinating animals will inevitably intersect with the anthera and pistil when taking nectar.

Nectar is a food source for bees. In agricultural cultivation, nectar is very important to attract the attention of pollinating insects.

The scent of flowers and the color of the crown leaves is a signal for the insects of the availability of nectar. The crown leaf that looks single-colored according to the vision of the human eye, actually has lines centered to the bottom of the flower when photographed with a film sensitive to ultraviolet light.

The lines centered on the base of the flower can be seen by insects and are a gesture of the location of the nectar. Different types of plants also produce nectar that attract other pollinating animals such as bats and birds. In contrast, flowers from plants that do not require pollinating animals (abiotic pollination) do not produce nectar.

Nectar consists of two types, floral nectar and extra floral nectar. The floral nectar is produced by the nectar gland, while the extra floral nectar is produced by the plant other than flowers. Extra floral nectar is intended to attract the attention of insects like ants that suck nectar as well as prey on plant destructive insects.
