I need help with this assignment it due in 3 day.

Create a dichotomous key that identifies the 10 leaves on the Common Leaves sheet. Look closely at those leaf samples and devise a dichotomous key that helps you identify them. Be sure that your dichotomous key contains only pairs of statements about a single characteristic. For example, a pair of statements might be:

leaf margin smooth

leaf margin toothed

However, you should avoid pairs of statements that do not address the same characteristic. The following pair, for example, would not be very informative in your key:

leaf margin smooth

leaf type needle-like
