Journal Entry:
How do you determine your chi square expected value when counting cells in different phases of cell cycle?
Learning Intentions
You can count cells from a prepared slide of an onion root tip that are in interphase or mitosis, record your data in a table, and then collect similar data in a new location of your onion root tip.
You can conduct a chi square analysis of cell cycle data.
You can design a investigation to test a variable that you think would influence cell cycle.
You can enroll in Gizmo class.
You can understand how Cell Division Gizmo works.
Closing Task:
You can collect data about cells in an onion root tip and statistically determine if location has an effect on the number of dividing cells.
