Teaching Guide | Mitosis: Evaluating the Effects of Lectin on Onion Root Tip Cell Division
This teaching guide helps educators to integrate the Mitosis: Evaluating the Effects of Lectin on Onion Root Tip Cell Division simulation into an advanced high school biology lesson. Students will develop skills to identify cell cycle phases in chromosome squash images, use a chi-square test to determine whether lectin exposure produces a statistically significant change in the proportion of dividing cells, and consider the real-world impact of affecting the rate of mitosis.
