All living things are made of one or more cells
There are an estimated 50-100 trillion cells in the human body.
All living things grow and develop
Inherited information carried by genes controls the pattern of growth and development of organisms.

organism Response to light Response to sound Respond to taste Respond to touch Respond to smells

• sweat, tears, mucus, sneezing, coughing, etc.
How about plants?
• gas exchange, vacuoles, dropping leaves
