360Science™: Environmental Effects on Mitosis

firewatch

In this lab, students carry out an investigation on how the addition of the auxin indole-3-acetic acid, IAA, impacts the rate of mitosis in an onion plant root. They will get the opportunity to compare onion roots grown with and without this additional IAA hormone.

Concepts

  • Biotic and abiotic factors
  • Cell cycle
  • Plant hormones
  • Chi-square analysis
