What is the difference between organs and organelles

Cells form tissues, and tissues form organs. Organelles occur in all eukaryotes. They are microscopic. But, organs are macroscopic and only found in animals and plants. Mitochondria , chloroplast , Golgi apparatus , endoplasmic reticulum , and the nucleus are organelles. Kidney, heart, liver, lungs, and brain are the organs in humans.

Flower, seeds, and spores are the reproductive organs in angiosperms. The cells in organs are highly specialized to perform necessary actions at a specific time.

A human body consists of 78 organs. Five organs among them, brain, heart, lungs, kidneys, and liver, are vital for the survival. The brain is the control center of the body, which coordinates other organs of the body through the nervous system. It is responsible for thoughts, feelings, general perception, and memory storage.

The heart pumps blood throughout the body. The lungs oxygenate the blood, which is circulated throughout the body, and remove carbon dioxide from the blood.

The kidneys remove metabolic wastes as well as the excess fluid from the circulating blood. The liver is the main storage of food. These mitochondria have an outer membrane, which encases the organelle, and an inner membrane, which folds over several times to create a multi-layered structure known as cristae. The fluid inside the mitochondria is called the matrix, which is filled with proteins and mitochondrial DNA.

Chloroplasts are another organelle that contain a double membrane and retain their own DNA. Unlike mitochondria, however, the inner membrane of chloroplasts is not folded.

They do, however have a third, internal membrane called the thylakoid membrane, which is folded. In addition, unlike mitochondria, chloroplasts are only present in plant cells. They are responsible for converting sunlight into energy through a process called photosynthesis. Other organelles like lysosomes are responsible for digesting and recycling toxic substances and waste. They are embedded with proteins called enzymes, which break down macromolecules, including amino acids, carbohydrates, and phospholipids.

Lysosomes are produced by a larger organelle called the Golgi complex, which manufactures other cellular machinery as well.

Whenever a cell dies, it self-destructs using its own lysosomes.

Organ Organelle 1. The organ is a structural part of the body that performs a specific function. The organelle is a functional unit of a cell and performs metabolic functions for the cell.

Various organs collectively make up the organ system. Various organelles collectively make up a cell. Each organelle has a specific function to do. Cell wall and cell membrane — protection. Mitochondria — energy production. Nucleus — protein synthesis and stores hereditary information.

Flagella and cilia — Movement. Ribosomes — protein synthesis and transport. 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. 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. Located in the organ system. Located in the cytoplasm plasma of the cell. Operates at the organism level and performs various life processes.
