4. 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

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

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

9. 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

13. 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

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

22. 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
