L.4 Mitosis Lab Activity
IB Assessment Statements Addressed in the activity:
2.5.1
2.5.2
2.5.3
Outline the stages in the cell cycle, including interphase (G1, S, G2), mitosis and cytokinesis
Describe the events that occur in the four phases of mitosis (prophase, metaphase, anaphase and telophase).
Explain how mitosis produces two genetically identical nuclei.
Objective




Identify and draw plant cells at various stages of the cell cycle (interphase, four mitosis phases, cytokinesis).
Identify and label chromosomes, chromatids, spindle microtubules, mitotic spindle in cells undergoing mitosis
Explain the cell cycle
Explain what is happening at each stage of mitosis
Materials
Microscope, prepared slide of onion root tip, pencil, lab worksheet
Procedure
1. Set-up a compound light microscope & turn on the light
2. Place a slide contain the meristematic or growth zone., which is just above the root cap at the very end of the tip
of the root.
3. Focus on low power, and then switch to medium or high power. Use your book and notes to help you find the
four stages of mitosis, cytokinesis and interphase.
4. Draw and Label the 6 cells at the 6 different phases of the cell cycle, and then describe what occurs during
these stages.
5. Once you are finished tell your teacher and she will give you a quick microscope quiz.
Procedure
1. Interphase. Below draw a cell in interphase and explain what happens during this phase, include details of G1,
S, G2.
