### Cell Cycle and Mitosis

Version: 1.0

This module introduces activities that allow students to walk through the cell cycle and mitotic cell division processes. As part of the activities, students learn about and apply knowledge of chromosomal behavior to identify different stages of mitotic cell division in plant and animal cells. They also calculate and compare mitotic indices for normally dividing and cancerous cells. Students apply quantitative and statistical concepts such as sample size, mean, standard deviation, and standard error of the mean to discuss the impact of sample sizes on interpretation of biological data (i.e., normally dividing and tumor cells, in this case).

This module contains exercises designed to help students describe the stages of cellular respiration and quantify the energy molecules produced. Students will predict the region of higher proton concentration in active mitochondria, calculate pH and predict pH changes in mitochondrial compartments. Students will also predict the effect of electron transport blockers on the proton gradient, pH, and energy production.

This module contains exercises designed to help students understand how solute concentrations affect the direction and rate of osmosis. Students are given different scenarios to predict the direction of water movement, calculate the rate of change in mass and create graphs to determine the isotonic concentration.
