The difference between pollen and nectar
Nectar is a sweet solution of sugars produced by the plant which is what bees collect to make honey. Flowers make this nectar to ensure bees get close enough to their male anthers which are covered in pollen, the powder you see on the bees back and legs. The flower needs the bee to transport this pollen to its female companion in order for fertilization to take place so it can produce a fruit. It is this process that ensures we get the vegetables and fruits and grains we love to eat.
