Answer No 2:
A group of tissues which work together make up an organ whereas, group of organs which work together will make up an organ system.
For example, the organs such as the heart, the lungs, the liver, the kidneys etc are made up of different tissues which work together so that these organs can perform their prescribed functions.
Answer No 3:
