[!] STUDY GUIDE: Big Ideas
Use to answer form questions!
1.All living things are made of cells. Cells are the
basic unit of life - the smallest living things.
2.Cells have specialized parts called organelles.
Each organelle has a specific job (mitochondria = energy, nucleus =
control center).
3.One cell can become trillions. A single fertilized
egg divides and specializes to build a whole organism.

How can a single cell become a whole human being?
You started as one tiny cell - smaller than a period on this page.
Now you have about 37 TRILLION cells working together. How is that
possible?

Q1 (NEW):
Explain why cells are NOT hollow or empty. What fills them?
Q2 (NEW):
How can one fertilized egg cell become 37 trillion cells in a human
body?
Q3 (INTEGRATION):
Why do cells with more mitochondria need more energy? Give an
example of a cell type that would have many mitochondria.
