The Cell Cycle
Remember the grammar!
Introductory phrases can tell us about when something happens. These phrases can
be good transitions in your writing!
Before _______________, (full sentence).
During ________________, (full sentence).
After _________________, (full sentence).
After that, (full sentence).
Activity
1. Read about cell division in the section called “Making More Eukaryotic Cells”
on p.153 in your textbook.
2. Use the reading to put the sentences below in order by numbering them in
the blank to the left.
3. For each sentence, choose the appropriate part of the cell cycle and whether
it happens “before,” “during,” or “after” that part.
4. Copy your completed sentences in order onto your notebook. Don’t forget the
commas!

The cell also grows.
The chromosomes separate into two
identical sets.
Flow Map
Based on the section you just read, do a flow map of the three stages of the cell cycle.
Use complete sentences, and underline the name of each stage. At the end, draw an
arrow back to the beginning to show that it starts again!
Phases of Mitosis
1. Read Figure 4 on page 154-155 of your textbook.
2. Use what you learn to complete the table below.
