Cells are the smallest unit of life. Thus, a cell requires all seven characteristics of living things. I use the acronym MR.GOSEA to remember these characteristics, which are identified and explained below:

M- Maintain homeostasis- All living things need to keep an internal balance. Examples would be blood pressure, blood sugar levels, heart rate, respiratory rate, etc. 

R- All living things must reproduce to ensure the survival of their species. 

G- All living things grow. 

O- All living things show some level of organization.  The levels of organization, from smallest to largest, are: atoms, molecules, organelles, cells, tissues, organs, organ systems, organisms. 

S- All living things respond to stimuli. 

E- All living things either make energy (via photosynthesis that is done within the chloroplast) or release energy (via cellular respiration in the mitochondria).

A- All living things adapt to their external environments.
