Question 1

From the provided text, the definition of tissue is "Groups of similar cells performing the same function are called tissues". So a group of cells performing the same function is a tissue.

The text states "A group of organs that carry on one of the major body function is known as a system". So a group of organs working together to perform the same function is a system.

According to the text, "An organism is made up of systems that perform its life functions". So systems make up organisms.
