LIFE’S MINIATURE FACTORY
Cell Structure
Function
1. Mitochondrion “Burns” fuel to produce
energy
2. Chloroplasts
Use the energy from
sunlight to produce food,
such as sugar, from raw
materials
3. Cell
Membrane
Determines what will
enter and/or leave.
4. Chromatin
Contains the “blueprints”
of the cell.
Cell Structure
Function
5. Nucleus
Directions the functioning of all of the other parts
6. Endoplasmic
Reticulum
Moves materials from place to place.
7. Vacuole
Neatly Stores materials until they are needed
8. Lysosome
Breaks down items so that they are easily useable.

3. What is the function of the chloroplasts?
4. What is the function of the vacuole?
5. Why don’t animals require chloroplasts?
6. Why do plants require cell walls?
7. Why do plants need larger vacuoles than animals?
