How can the characteristics of different plant species be used to compare them?

Let's investigate

In this virtual lab, you will use the four characteristics described in this lesson (seed size, seed shape, leaf shape, and stem type) to compare plant species. Examine the characteristics of the plant specimen on each tab. Use the accompanying worksheet to record your observations and use your data to answer the analysis questions.
