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 ribosome's

2. Ribosome's Function: makes proteins Found in all cells, prokaryotic and

eukaryotic

3. Endoplasmic Reticulum (ER) Nickname: “Roads” Function: The internal delivery

system of the cell

Ribosomes

Endoplasmic Reticulum 2 Types:

1. Rough ER: Rough appearance because it has

ribosome's Function: helps make proteins, that’s

why it has ribosome's

2. Smooth ER: NO ribosome's 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

5. Lysosomes: circular, but bigger than ribosome)

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

7. Vacuoles Function: stores water

This is what makes lettuce crisp When there is no water, the plant wilts

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
