1.How did scientists discover that all living things are made of cells?

Scientists discovered all livings things are made up of cells by using microscopes and going out to the wild forest and jungle bring back dead bodies and experiment on them.  

2.How did Pasteur’s experiment with the flasks help disprove the idea that living things could just appear or come from nonliving things like water and air?

It proved that some things/chemicals that interact with o2 for varying periods of time will have differences in looks

3.Why are nutrients needed for living things? Describe the difference between living and nonliving things.  

The body won’t function properly if there aren’t any nutrients.
