Question
Lab 23 nvertebrates and vertebrate Experiment 1: Symmetry in Common Objects symmetry can be seen in everyday objects similar to that of the symmetry seen in organisms. Materials Images of Common Lab Equipment Procedure 1. Review the objects listed below (many of these can also be found in your lab kit). 2. Indicate the type of symmetry each item displays next to the image in the Post- Lab Questions section. Hint: It is helpful to draw lines of symmetry over the objects and observe objects from different angles. 3. For each item, explain why you chose the type of symmetry you did. a Peti Dish c Test Tube Rack d Wash Bottle e, Graduated Cylinder Tongs 2013 eScience Labs, LLC. All Rights ReservedExplanation / Answer
a. petri dish- radial symmetry; because petri plate can be divided into similar halves by passing a plane at any angel along a central axis.
b. funnel- radial symmetry; because funnel can be divided into similar halves by passing a plane at any angel along a central axis.
c. Test tube rack- bilateral symmetry; because test tube rack can be divided into equivalent right and left halves by only one plane.
d. water bottle- bilateral symmetry or radial symmetry
e. graduated cylinder- radial symmetry; because graduated cylinder can be divided into similar halves by passing a plane at any angel along a central axis.
f. tongs- bilateral symmetry; because test tube rack can be divided into equivalent right and left halves by only one plane.
