This document summarizes the structures and functions of organelles in plant and animal cells. It describes the nucleus, which holds DNA, the nucleolus, ribosomes which make proteins, and the endoplasmic reticulum which transports materials within the cell. The Golgi complex packages and transports materials, lysosomes break down waste, and mitochondria produce energy. Plant cells also contain vacuoles for water storage, chloroplasts for photosynthesis, and a cell wall for support and protection.

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

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

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

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
14. Eukaryotic Cell Organelles and
Function
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
17. Now let’s talk about structures only
found in PLANT Cells!!

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

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
