Become an active participant in your own learning. Witness the effects of phototropism in plants by investigating it—not just reading about it.
Get an upclose look at the inside structure of growing plants to understand why they bend toward the light. Carry out virtual experiments similar to those performed by Charles Darwin, Peter Boysen-Jensen, and Fritz Went to learn about phototropism in plants.
• Discover what causes plants to bend toward the light. • See examples of tropic responses in plants. • Predict how a plant will respond to various factors and then test your hypotheses. • Determine the role that a plant’s coleoptile plays in sensing the direction of incoming light. • Review the studies of Darwin, Boysen-Jensen, and Went concerning phototropism. • See how the chemical auxin affects phototropism.
App Features With this app, you will be able to: • Design your own interactive experiments based on those of famous scientists. • Make hypotheses and then analyze data to draw conclusions. • Receive hints and tips as you perform virtual investigations. • Test your knowledge of what you have learned and what you need to know. • Want more?
