What are the differences between organs and organelles?

Question

Accepted Answer

Basis of Differentiation
Organs
Organelles

Definition
Organ refers to a collection of tissues that perfom similar functions in the body
Organelles are microscopic, specialized structures found inside cells, which carry out sepcific life processes

Examples
Heart, brain, lungs, stomach, kidneys, and intestines 
Nucleus, mitochondria, endoplasmic reticulum, Golgi apparatus, and chloroplasts

Composition
Organs are composed of tissues
Organelles are composed of a single cell

Larger unit
They are part of the organ system in the body. 
They are a part of cells

Location
They are located in the organ system
They are located in the cytoplasm of the cell.

Found in unicellular/multicellular organisms
Organs are only found in multicellular organisms
Organelles are found in unicellular and multicellular organisms

Size
Organs are macroscopic and easily visible to the naked eye. 
Organelles are microscopic and only visible when viewed under an electronic microscope

Function
Organs perform specific vital life processes in the body
Organelles perform specific processes in the cell

Level of operation
Organs operate at the organism level and perform a number of life processes
Organelles operate at the cell level and perform a number of cellular processes.
