1. In a plant, where are cells “continually dividing?”
2. Sketch a root and label. Please include the following parts: root cap, apical meristem, root hairs, xylem
and phloem.
3. From where in the root are new cells produced?

Cell Cycle Lab
Objective: To determine the relative number of cells undergoing the different stages of the cell cycle.

Metaphase

Anaphase

Telophase

Graph: Make an appropriate graph of the class average – showing the % of cells in each stage.
Analysis:

1. Which phase of the cell cycle had the most cells?
2. Why do you think the phase to question #1 had the most cells?
3. If your data had many cells undergoing mitosis, to which part of an onion root do you think your cells
belong? Why?
4. If your data had a few cells undergoing mitosis, to which part of an onion root do you think your cells
belong? Why?
