The time has come to experience science like never before! Complete virtual experiments, make predictions, and draw conclusions. Bring science to your device and take control of your learning.

Conduct experiments similar to those performed by the scientist Joachim Hämmerling to discover the role that the nucleus plays in cells. Using a scalpel and a micro-injector in a virtual lab, cut a single-celled alga into different parts and then remove its nucleus.

• Discover the unique features of the giant unicellular species of Acetabularia.
• Repeat Hämmerling’s experiments on algae.
• Predict whether an alga will survive if its base, stalk, or cap is removed.
• Carry out experiments to test your hypotheses.
• Find out the function of the nucleus in cells.

App features:
• Carry out experiments in a virtual, interactive environment.
• Receive step-by-step support as you perform investigations.
• Predict the outcomes of your experiments and test your hypotheses.
• Demonstrate what you learn by taking quizzes.
