The document discusses stimuli and responses in plants and animals. It defines a stimulus as any action that causes an organism to react, and a response as how the organism reacts to a stimulus through changes in behavior. There are two types of stimuli - external stimuli that come from outside the organism, and internal stimuli that come from inside. Organisms can have either muscular responses through muscle movement or glandular responses through substance production by glands.
