Objective 2.79: understand that plants respond to stimuli
Stimuli is changes in the environment, examples are temperature and light changes.
Plants have receptors to detect stimuli and respond
the responce is growth.
growth in responce to stimuli is called TROPISM
trpism in responce to:
gravity; geotropism
light; phototropism
the connection between the receptor and the responce usually takes the form of plant hormones, often known as plant growth regulators
an example of this would be AUXIN
good concise notes well done
