Let’s look at the pie chart on the left labeled “Cell Cycle.” It shows how much time a cell spends in each phase.
The big part of the pie is labeled
Interphase, and it includes:
- G1 (cell growth)
- S (DNA replication)
- G2 (preparation for division)
Together, these three phases make up Interphase.
The smaller slices are:
- Mitosis
- Cytokinesis
- Checkpoints (but note: checkpoints aren’t separate time periods — they’re control points during other phases)
Now, look at the bar graph below the pie chart. It says:
> Percentage of time spent in cycle
> INTERPHASE | MITOSIS
We need to fill in the percentages.
From biology knowledge (and standard teaching materials), we know that:
✔ A typical cell spends about
90% of its time in
Interphase.
✔ The remaining
10% is spent in
Mitosis (which includes cytokinesis in many contexts, though technically cytokinesis overlaps with mitosis).
In the pie chart, you can see that Interphase takes up almost the whole circle — way more than half. That matches 90%.
Also, the legend shows:
- White = Interphase → biggest slice
- Dotted = Mitosis → small slice
- Striped = Cytokinesis → even smaller or part of mitosis
- Gray = Checkpoints → not a time phase, so not counted in percentage
So, for the bar graph:
→ INTERPHASE =
90%
→ MITOSIS =
10%
(Note: Sometimes cytokinesis is included in mitosis for simplicity in basic bio classes.)
Final Answer:
INTERPHASE: 90%
MITOSIS: 10%
