The ability to perform these and other functions is part of their organization. Living things increase in size.

What makes cells important to keep organisms alive?

How do single-celled organisms perform life processes?

Single celled organisms perform various life processes needed for the sustenance of their life by using their specialized cell organelles. These organelles act in the similar manner as the tissues and organ systems found in multicellular organisms to carry out these life processes.

How are cells function to keep organisms alive?

Metabolism is one of the processes that keep us alive. We die whenever cells stop their metabolic activities. Metabolism is the set of chemical reactions in cells that allow organisms to grow, reproduce, walk, talk, breath, think, etc. You get the idea.

How do single celled organisms respond to their environment?
