Activity ANSWER KEY Cell Structure and Function Directions: Label the organelles of the cell and write a brief description of the organelle
function.
1. Animal Cell: Animal cells are eukaryotic cells.
2. Endoplasmic reticulum (ER): ER is a network of passageways that carries materials
from one part of the cell to another.
3. Nucleus: The Nucleus controls activities of the cell and contains the hereditary
material DNA.
4. Vacuole: A Vacuole is Found in some animal cells, vacuoles store water, food, and
wastes.
5. Ribosomes: Ribosomes are the protein factories of the cell.
6. Cytoplasm: Includes everything found inside of the cell membrane except for the
nucleus.
7. Cell Membrane: Separates the inside of the cell from the outside environment and
allows some materials to pass in and out of the cell.
8. Cytoskeleton: Gives the cell its shape and provides strength for the cell structure.
9. Lysosome: Contains chemicals that break down food particles and worn-out cell
parts.
10. Mitochondria: Sometimes referred to as the “powerhouse”, it produces most of the
cell’s energy.
11. Golgi Body: The Golgi Body or Apparatus receives materials from the ER, packages
them, and sends them to other parts of the cell.
