Four students are working on a human body project for their science class. They cannot agree on the basic unit of structure and function in the human body where basic life processes are carried out. These basic processes are getting energy from food, removal of waste molecules, response to stimuli, reproduction, movement, growth and repair. They debated their ideas as follows:

Paul’s argument: Tissues are the basic unit of structure and organs are the basic units of function.

Tia’s argument: Cells are the basic unit of structure and organs are the basic unit of function.

Margy’s argument: Cells are the basic unit of structure and function.

Ray’s argument: Organs are the basic unit of structure and function.


Which student do you agree with, if any? In 3-4 sentences (or you can record yourself speaking your answer and link it here) describe your thinking. Provide an explanation for why you think the way that you do.
