Eukaryotic Cell Organelles and Function
1. Nucleus– Nickname: “The Control Center”– Function: holds the DNA– Parts:
• Chromatin: strands that contain genetic material
• Nucleolus: dark spot in the middle of the nucleus that helps make ribosomes
– Plant and animal cells

3. Endoplasmic Reticulum (ER)– Nickname: “Roads”– Function: The internal delivery system of
the cell – Located: Cytoplasm– Plant and animal cells

4. Golgi Complex– Nickname: The shippers– Function: packages, modifies, and
transports materials to different location inside/outside of the cell
– Appearance: stack of pancakes– Located: Cytoplasm– Plant and animal cells

5. Lysosomes: circular, but bigger than ribosomes)
– Nickname: “Clean-up Crews”– Function: to break down food into particles
the rest of the cell can use and to destroy old cells
– Located: Cytoplasm– Plant and animal cells

6. Mitochondria– Nickname: “The Powerhouse”– Function: Energy formation
• Breaks down food to make ATP– ATP: is the major fuel for all cell activities that
require energy
– Located: Cytoplasm– Plant and animal cells

Vacuole
Eukaryotic Cell Organelles and Function
7. Vacuoles– Function:
• Plant Cells– Very large– stores water– This is what makes lettuce crisp
» When there is no water, the plant wilts
• Animal Cells– Smaller than in plant cells– Stores/releases waste products – used in cellular digestion
– Located: Cytoplasm

Chloroplasts
Eukaryotic Cell Organelles and Function
8. Chloroplasts– Function: traps energy from the sun to
produce food for the plant cell– Located: Cytoplasm– Green in color because of chlorophyll, which
is a green pigment– Plant cells

the cell membrane– Located: Found outside the cell membrane
in plant cells

10. Cell Membrane– Functions:
• separates the inside of the cell from its environment
• Controls what substances enter and leave the cell
– Oxygen, carbon dioxide, wastes, food, etc…
– Located:• In plant cells, it is to the inside of the cell wall• In animal cells, it is the outermost part of the cell
