Nectar, in botany, is a liquid made by the flowers of plants. It is sweet because it has sugar in it. Plants make nectar to attract pollinating animals. It is made in glands called nectaries. The nectaries are usually at the bottom of the perianth of the flower. This means the animal trying to get the nectar has to touch the parts of the plant that are used for reproduction. By doing this, the animal getting the nectar helps the plants reproduce.
