In this video segment from Cyberchase, Bianca wants to learn why her plants keep dying, so she transports them in a carriage to the New York Botanical Garden. A helpful plant expert shows her some patterns in plants, including bilateral and rotationa...l symmetry, before discovering the pattern that may be killing Bianca's plants. Closed captioning. Run time 03:25.
