Organs and organelles function combined to keep the cells, tissues and other parts of the system, an organism alive. Organs and organelles are found in all multicellular organisms.
All multicellular organisms have the same levels of classification –
Cells forms tissues, tissues forms organs, organs form organ systems, and organ systems make organisms.
| Cell – Tissues – Organs – Organ Systems – Organisms. |
Read on to explore the difference between organs and organelles in detail.
Organ vs Organelle
For better understanding, let us learn more in detail about the difference between the Organ and Organelle.
| Organs | Organelles |
|---|---|
| Organs are part of the body. | Organelles are part of the cells. |
| Found in multicellular organisms | Found in all eukaryotic organisms |
| Organs collectively form organ systems | Organelles contribute to form a cell. |
| Performs specific life processes in the body. | Performs a specific process within the cell. |
| They are macroscopic in structure. | They are microscopic in structure. |
| Brain, Heart and Lungs are a few examples of organs. | Mitochondria, Nucleus and Golgi apparatus are a few examples of organelles. |
Organs
An organ is a collection of tissues performing a similar function. An organ is large and forms a part of the body. A group of organs together comprises organ systems. Organs are a large part of an organism. In general, the human body consists of about 78 organs and among them, the brain, heart, liver, lungs, kidneys, and are the five vital organs for the life existence.

Organelle
An organelle is a small, specialized structure found inside cells which carries out a specific life process. Organelles are microscopic and collectively form a cell. They are the functioning unit of all unicellular organisms, including amoeba, bacteria, fungi, protists, etc.

Frequently Asked Questions
What is an organ?
Organ is the collection of tissues performing similar functions. The eyes, ears, nose, hands, and legs are a few organs of the human body.
What is an organelle?
An organelle is a minute cellular structure that performs specific functions within the cell. They are suspended in the cytoplasm of eukaryotes.
Which is the largest organelle in a cell?
The nucleus is the largest organelle in a cell. It is located in the centre of the cell and is surrounded by a membrane. It consists of a dense structure called a nucleolus.
Is DNA an organelle?
No, DNA is not an organelle. It is a macromolecule present inside an organelle called the nucleus.
Which is the major difference between an organ and an organelle?
An organ is a collection of tissues performing specific functions in the human body. On the contrary, organelles are cellular structures performing specific functions within the cell.
