What is an organelle?
2.
Name two organelles that are found only in
plant cells.
3.
What organelle is called the “power-house”
of the cell?
4.
Think of hardworking, energy-burning

Exercise 3
Questions
1. What is an organelle?
A structure within a cell that has a specific function.
2. Name two organelles that are found only in plant cells.
Cell Wall and Chloroplasts
3. What organelle is called the “power-house” of the cell?
Mitochondria
4. Think of hardworking, energy-burning muscle cells.
Which organelle would you expect to see a lot of in
muscle cells?
Mitochondria because mitochondria are the organelles
that are responsible for producing energy for the cell.
