Differentiate Between Organs and Organelles

Organs and organelles function combined to keep the cells, tissues and other parts of the system to keep 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.

Organs

An organ is the collection of tissues performing the 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, a human body consists of about 78 organs and among them, brain, heart, liver, lungs, kidneys, and are five vital organs for 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, Protista, etc.

Difference Between Organ and 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 all multicellular organisms Found only in unicellular organisms
Organs collectively form organ systems Organelles contribute to form a cell.
Performs specific life process in the body. Performs a specific process within the cell.
They are macroscopic in structure. They are microscopic in structure.
Brain, Heart, Lungs, are a few examples of organs. Mitochondria, Nucleus, Golgi apparatus are a few examples of organelles.

Frequently Asked Questions

What is an organ?

Organ is the collection of tissues performing similar functions. Eyes, ears, nose, hands, legs, are 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 prokaryotes and 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 nucleolus.

Is DNA an organelle?

No, DNA is not an organelle. Instead, it is present inside an organelle called nucleus.

Which organelle is the major difference between an organ and an organelle?

Organ is a collection of tissues performing specific functions in a human body. On the contrary, organelles are cellular structures performing specific functions within the cell.
