A group of tissues makes up an Organ. The Organs are specialized to perform a specific function in the human body system. A human body consists of 78 internal Organs performing a specific function. The main Organs in the body are the Heart, Kidney, Liver, Brain, and Lung. The heart is the key component of the circulatory system and performs the function of pumping blood to various parts of the body. The kidney performs excretory functions by removing metabolic wastes and fluids from the body. The liver is the primary Organ for metabolism where various metabolic processes occur leading to the production of useful metabolites. The brain keeps the Organs systems coordinated. The lungs supply oxygen to the tissues and eliminate carbon dioxide from the body system.

What is an Organelle?
An Organelle is a component of the cell. In single-celled Organisms like the bacteria, the Organelle is the functional analog.
In eukaryotic cells, the Organelles are found in the cytoplasm. The different cell Organelles present in the eukaryotic cell are the cell wall, nucleus, mitochondria, endoplasmic reticulum, cell membrane, Golgi apparatus, ribosomes, flagella, vacuoles, centrioles, cilia, lysosomes, and, peroxisomes.
The prokaryotic cells lack membrane-bound Organelles. The prokaryotic cell Organelles include nucleoid, cell membrane, cytoplasm, cell wall, ribosomes, and flagella.

Each Organelle has a specific function to do.
Differentiate Between Organs and Organelles:
To Differentiate between Organ and Organelle, there are certain parameters that you must understand.
-
The Organs and the Organelles are entirely different but the Organ cannot perform any function in the absence of the cell Organelles.
-
The Organelles are the simplest form and form the basic level of Organization. The Organs having the same origin and function form an Organ system giving rise to higher levels of the Organization.
-
There are various parameters to consider to differentiate between an Organ and an Organelle. The table below depicts the differences between them both concerning various parameters.
Organ vs Organelle
|
Parameter |
Organ |
Organelle |
|
Definition |
It is defined as a group of tissues having the same origin and same function. |
It is defined as the component of the cell performing a specialized and unique function. |
|
Location |
Located in the Organ system. |
Located in the cytoplasm (plasma of the cell). |
|
Operation |
Operates at the Organism level and performs various life processes. |
Operates at the cell level and performs various cellular processes. |
|
Size |
Macroscopic and are visible to the human eye. |
Microscopic and are visible when viewed under an electronic microscope only. |
|
Presence |
Found in all multicellular Organisms. |
Found in both multicellular and unicellular Organisms. |
|
Degree of Organization |
Forms the highest level of Organization i.e. the Organ system. |
Forms the lowest and simplest degree of Organization i.e. the cells. |
|
Examples |
Internal Organs like Heart, Liver, Kidney, Lungs, Brain, skin, stomach, etc. |
The cell membrane, nucleus, mitochondria, lysosomes, centrioles, vacuoles, chloroplast, flagella, cilia, etc. |
Let’s differentiate the Organ and Organelle based on their functions happening in the entire body system.
|

Organelle |
|
Respiration |
At the Organ level, lungs along with bronchioles and bronchi perform the respiratory function. |
Mitochondria are considered as the primary site for respiration at the basic level. |
|
Energy Production |
The liver is the key site for all metabolic processes. Various components undergo metabolism and produce energy. |
Mitochondria is the key site for energy production. It produces energy in the form of Adenosine Triphosphate (ATP). This is the reason, it’s also called “Powerhouse of the cell”. |
|
Protection |
Skin, the largest Organ in the body system protects the internal Organs from the external environment. |
The cell wall and the cell membrane protect the internal cell Organelles. |
|
Movement |
The blood is the primary Organ that’s useful in transporting various substances to internal Organs and tissues. It carries oxygen to tissues, brings carbon dioxide from the lungs, and carries waste products to the kidneys for excretion. |
Flagella and cilia are the cell’s Organelles that aid transportation. Cilia are present in the nose, lung lining, intestine lining, vas deferens lining, and fallopian tube lining. Human male gametes possess a flagellum that aids in movement and locomotion. |
|
Phagocytosis |
The cells of the immune system like macrophages, dendritic cells, and neutrophils perform phago |
The lysosome is the only Organelle of all the cell Organelles known to perform phagocytosis. |
Fun Facts
Example: stomach and heart.
-
In the body system, the large intestine is smaller than the small intestine. They are named conversely considering size as a parameter.
-
A few cell Organelles are large enough to resolve and are visible under the light microscope.
Example: Nucleus.
More About the Difference Between Organs and Organelles
This text made you understand the meanings of Organs and Organelles. It also made you understand the difference between both of them. It also gave some fun and very informative facts.
Students shall understand that understanding and comprehending are two different things. You might think that everything that you have studied was understandable but once you decide to check how much you have comprehended, you shall take up a self-assessment.
Based on these results, you would know the exact state of your preparations and this way, you can also prepare the next immediate plan of action.

Playing the yet game may help you keep your morales up. ‘Yet’ game is like when you do something, never say that you can’t do it just say I have not done it yet. It is one of the most amazing exam tricks, it is very useful. For example, you are not good at maths so you should not say that you can’t do maths you should rather say I am not good at maths yet. It is like a mental game, you are being honest in the present and also opening metal doors for the future.
If you want to take off your pressure you just need to find out your plan B and also find out the reasons to be excited about it.
