Nectar
Explanation: 

Detailed explanation-1: -Nectar is a fluid substance secreted by flowers in plants. It is rich in sugar. It helps in attracting pollinating agents like bees and butterflies.

Detailed explanation-2: -Plants rely on bees and other insects to reproduce and so they have adapted, over time, to become more attractive to them. Bees are drawn to plants with open or flat tubular flowers with lots of pollen and nectar. A flower’s scent can have particular appeal to bees, and its bright colours may lure the bees in.

Detailed explanation-3: -Nectar is the sweet fluid produced by flowers to attract bees and other insects, birds and mammals. Worker bees drink the nectar and store it in a pouch-like structure called the crop.

Detailed explanation-4: -Bees collect nectar from flowers. Nectar is the sweet liquid that entices the bees to the flower. The bees climb onto or into the flower and suck up the nectar with their straw-like mouth and collect it in a little sac called a crop. They also collect pollen on their legs.

Detailed explanation-5: -Nectar is basically a sugar solution composed of one disaccharide (sucrose) and two hexoses (glucose and fructose).
