Mitosis Lab Activity
Learning Target: Copy the learning target from the board in the space below.
Part 1: Whitefish Blastodisc (a small cluster of fish cells after fertilization)
Part A: Viewing Cells in Different Parts of M Phase
Complete the stage descriptions and LABEL the pictures to the right in the table below.
Stages of Cell
Division
Stage(s) Description
Labeled Picture of a Cell as it
Appears Under a Microscope
Interphase
nucleus, cell membrane, cytoplasm
M Phase
Mitosis
Prophase
cell membrane, cytoplasm, chromosomes,
chromatid, centromere
M Phase
Mitosis
Metaphase
cell membrane, cytoplasm, chromosomes,
chromatid, centromere, spindle fibers
M Phase
Mitosis
Anaphase
cell membrane, cytoplasm, chromosomes, ,
spindle fibers
M Phase
Mitosis
Telophase*
AND
Cytokinesis*
cell membrane, cytoplasm, chromosomes,
cleavage furrow , nuclei reforming
*Note: these stages of M Phase are happening simultaneously
Part B: Number of Cells in Interphase vs. M Phase
What is different about the four cells identified by the boxes? What can be seen in them?
Why are most of the cells different from the four cells in boxes? In other words, why are most of the
cells unlike those cells in the boxes?
Part 1 Conclusion Questions
1. How can animal cells be told apart from plant cells?
2. Why do chromosomes become visible during M Phase?
Part 2: Allium (onion) Root tip
Part A: Drawing and Labeling Cells in Different Parts of M Phase
Find a SINGLE cell in each of the stages below under the microscope
using the prepared slides. Then draw and LABEL the cell in the right
column of the table below.

Part B: Number of Cells in Interphase vs. M Phase
How can dividing cells (in M phase) be identified when
compared to non-dividing cells (in interphase)?
How many cells are in mitosis in the picture to the right?
Circle them on the picture.
Part C: Identifying Cells in Interphase of M Phase
Complete this part of the lab individually. Identify the cell cycle phase (interphase or M phase)
displayed by the cell directly under the pointer in the numbered microscopes.

Part 2 Conclusion Questions
1. How is cytokinesis different in plant cells compared to animal cells?
2. Once a cell has completed the cell cycle, what can be said about the two newly divided cells
compared to the parent cell? (Hint: discuss genetics and/or DNA.)
