 Compare your table to the table below. Make an corrections as needed.

Looking at your corrected table, answer the following questions. 2. What does the pattern of data for “makes seeds” say about the relationships among the 5 plants and alga? 3.What does the pattern of data for “grows > 10 cm tall” say about the relationships among the 5 plants and alga?

 In a team of two, use all of the data in your table to create a diagram in your notebook that summarizes how the 5 plants and alga are related.

 Trade notebooks with the group next to you. Do not tell them how to read the diagram. Try to determine the patter of relationships on your teammate’s diagram.  Look for similarities and differences.

 Now explain how to read the diagram to your teammates.  Both members of the team need to fill out a feedback card and give it the team you traded with.  Revise your diagram with a different colored pen or pencil.

 On a big piece of paper, work with your partner to draw your final diagram.

Analysis 5. Using a different colored pen/pencil, revise your answer for #1, based on what you have learned using this activity. 6. Select 1 diagram from your class that you think most clearly represents the relationships among the organisms. Write 3 sentences explaining what the diagram has that makes it easy to understand.

Draw this diagram. This diagram shows the relationship between plants and alga. Does the shape of this diagram remind you of any particular living organism?

Looking at scientific relationships Using the diagram that you and your partner created place the following characteristics onto the tree where you see stars. A. Has chloroplast (green color) B. Has cells C. All species have more than 1 cell. D. Grows > 10cm tall E. Makes seeds F. Makes cones G. Makes flowers
