3. Eukaryotic Cell Organelles and
Function
1.Nucleus
Nickname: “The Control Center”
Function: holds the DNA
Parts:
1.Nucleolus: dark spot in the middle of the
nucleus that helps make ribosomes

Function
2.Ribosomes
Function: makes proteins
Found in all cells, prokaryotic and
eukaryotic

6. Eukaryotic Cell Organelles and
Function
3.Endoplasmic Reticulum (ER)
Nickname: “Roads”
Function: The internal delivery system of
the cell

8. Endoplasmic Reticulum
2 Types:
1.Rough ER:
Rough appearance because it has
ribosomes
Function: helps make proteins, that’s why it
has ribosomes
1.Smooth ER:
NO ribosomes
Function: makes fats or lipids

4.Golgi Complex
Nickname: The shippers
Function: packages, modifies, and
transports materials to different location
inside/outside of the cell
Appearance: stack of pancakes

12. Eukaryotic Cell Organelles and
Function
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

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

Function
7.Vacuoles
Function: stores water

This is what makes lettuce crisp
When there is no water, the plant wilts

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

Function: provides support and
protection to the cell membrane
Found outside the cell membrane in plant
cells
