Behavior
Reflex Action is the term that describes the way an organism responds to stimuli. It receives stimuli through its senses and reacts with movement, or for a plant growing towards or away.

This encompasses various physical, physiological, and behavioral changes that occur from the initial formation of the organism to its maturity and eventual decline. Development can include processes such as cell division, differentiation, and aging.
