Putting plants into groups
To understand that plants can be grouped by the different ways they reproduce.
Not only is it important to tell the difference between living things, but it is easier to study them if they are in groups. Moths belong to a group called insects.

What about plants? How are they put into groups? The most important difference between plants is how they reproduce.
