Question

What is the difference between an organ and an organelle ?

Answer 1

A group of tiisues which have common origin and perform similar function make up an organ. Organ is the collection of tissues performing similar function. Organ is large and forms a part of the body. Organs together form organ systems. Organelle is a small structure which lies inside the cell and performs certain functions of the cell. Organelles are microscopic and lie inside the cell. Organelles collectively form a cell.

Organelles function to keep a cell alive while organs perform functions to keep an organism alive [multicellular organisms]. Organs are are made up of tissues and tissue are further made up of cells, and as we know cells are alive due to organelles.
