Difference Between Organ and Organelle -


Organ vs Organelle

Organ is a structural unit in an organism that is a collection of tissues and performs a specific function. Two or more organs performing related functions in the body of an organism join together to make an organ system. Organs are found in higher biological systems like plants, animals and human beings. Examples of organs in human beings are heart, kidney, lever etc that perform specific functions for the body. Organelle, on the other hand is a part of a cell that is in itself a specialized unit and capable of performing a specific function for the cell. There are other differences also that will be discussed in this article.

It is clear then that organelles are very small subunits inside a cell. Cells are building blocks of life and all living beings are made up of cells. When a group of cells join together, they make up tissues that perform specific functions such as muscles, tendon, or nerves. Organs are a group of tissues that perform a specific function. Just like organelles perform different functions, different organs perform different functions. For example, heart has its own function and so on. When two or more organs combine, they form an organ system having specific job such as digestive system, reproductive system, nervous system and so on.

Talking of human body, there are many organ systems and organs that are made up of billions of cells. These cells in turn have tiny organs inside that are known as organelles and perform functions for the cell on a very small scale. One can consider organelles to be similar to organs on a much smaller scale. Organelles perform functions to keep a cell running. For example, ribosomes build proteins from RNA blueprints.

In brief:

Difference Between Organ and Organelle

• An organ is a specialized body part of a human being, a plant or an animal (such as heart, liver, kidney). This organ is made up of tissues that are in turn made up of cells. Organelles are inside the cell and perform functions specifically for the cell just like organ does for the organism.

Key Difference – Bacteria vs Cyanobacteria   Bacteria and cyanobacteria are prokaryotic microorganisms. Cyanobacteria are the largest bacteria found in aquatic environments. Both groups include unicellular microscopic organisms, and both possess a simple body structure. Cyanobacteria have a characteristic blue-green colour due to its unique pigments. They are referred as blue-green algae too. Some bacteria are able to photosynthesize. But most of the bacteria are heterotrophs. Cyanobacteria are capable of photosynthesizing. The key difference between bacteria and cyanobacteria is that bacteria do not produce free oxygen during their photosynthesis while cyanobacteria are capable of producing free oxygen during the photosynthesis.

Categorical vs Quantitative Data   Although both categorical and quantitative data are used for various researches, there exists a clear difference between these two types of data. Let us comprehend this in a much more descriptive manner. In statistics, observations are recorded and analyzed using variables. The variables are categorized into classes by the attributes they are used to measure. Categorical and Quantitative are the two types of attributes measured by the statistical variables. Through this article let us examine the differences between categorical and quantitative data. What are Categorical data? Qualitative variables measure attributes that can be given only as a property of the variables. The political affiliation of a person, nationality of a person, the favorite color of a person, and the blood group of a patient can only be measured using qualitative attributes of each variable. Often these variables have limited number of possibilities and assume only.......READ
