As part of our learning about biological classification (week 31), you completed the Biological Classification POGIL assignment. Model 4 from that assignment begins with a dichotomous key that helps you determine which kingdom your unknown organism belongs to (Pro Tip – open up that assignment). We are going to be focusing on photosynthetic organisms (the answer to the ? box) which we know are called Plants! A dichotomous key can look like a flow chart (like the POGIL) or it can look like a series of questions similar to a choose-your-own-adventure book where one question leads to the next and eventually you figure out the identity of the organism. To begin, watch the video below to see you to use a dichotomous key:
Now, imagine you are out for a walk in the woods. You look up at the tall trees and down at the forest floor. How do you know what’s what? Is that plant native or a weed?
