In this lesson, you had a look at the difficulties of using leaves as a feature in classification. You can say that leaves are useful in describing plants. But leaves are not useful if they are the main feature used to classify plants.
Now that you know that choosing a feature is not as easy as you might have thought, you can learn from the work of botanists in the past. From there, you will look at how modern botanists classify plants.
Usually at the end of a lesson, there is a summary for you.
This time, it is your turn. Go to Exercise.
