BIOL MISC Student Exploration: Cladograms Gizmos with all the
correct answers
, Name: ALAQ HAMEED Date:
Student Exploration: Cladograms
Vocabulary: adaptation, amino acid, amnion, artiodactyls, bipedal, clade, cladistics, cladogram,
convergent evolution, evolution, flower, mammary glands, molecular, morphological,
multicellular, parsimony, sagittal crest, phloem, selenodont teeth, SNP, xylem
Prior Knowledge Questions (Do these BEFORE using the Gizmo.)
1. Look at the images below. Which two organisms do you think are most closely related?
Turtle and Deer
Worm Deer Turtle
2. Why do you think so? Because they both are vertebrates (have a backbone) but the worm
doesn’t.
Gizmo Warm-up
Cladistics is a method of hypothesizing the evolutionary
relationships between species. A cladogram is a branching diagram
that illustrates these relationships. For example, the cladogram on the
right shows that deer are more closely related to turtles than to
worms. In the Cladograms Gizmo, you will use morphological
(physical characteristics) and molecular data to create cladograms.
To begin, make sure Plants is selected for the Organism group and Morphological is selected
for the Data type. Click on one of the characteristics to the left of the table on the TABLE tab.
Information about the characteristic will be shown on the ORGANISM tab.
Using the information on the ORGANISM tab, describe each of the characteristics below.
Xylem and phloem: Xylem and Phloem are tissues in plants that transport water and
solutes up the plant (phloem) and food down the plant (xylem).
Flowers: A flower is a part of a plant containing reproductive organs (stamen and carpel)
surrounded by brightly colored petals.
Multicellularity: A multicellular organism is composed of more than one cell.
