Pollen Grains:

The Calling Cards of

Flowers

As they fly around from flower to flower,

honeybees collect the precious nectar from

which they eventually make honey. At the

same time, they also collect flower pollen

to feed the bee larvae in the hive. Have you

ever watched a bee that just visited a

flower? As it emerges from the flower, it

will often appear covered with yellow

powder from head to foot. You shouldn’t be

surprised, then, if a few of those pollen

grains end up in the honey.

Pollen grains are interesting objects to

study under a microscope. You will be able

to discover lots of different shapes and

surface structures among them. The round,

prickly pollen of a sunflower, for example,

looks completely different from the air-

bladder-equipped pollen grains of a pine

tree or spruce. There are scientists who

specialize in pollen, using a microscope to

study the pollen composition of all sorts of

samples — among other things, to

determine the country from which a honey

sample came.
