Plant physiology is a subdiscipline of botany concerned with the functioning, or physiology, of plants. Closely related fields include plant morphology (structure of plants), plant ecology (interactions with the environment), phytochemistry (biochemistry of plants), cell biology, and molecular biology.
Fundamental processes such as photosynthesis, respiration, plant nutrition, plant hormone functions, tropisms, nastic movements, photoperiodism, photomorphogenesis, circadian rhythms, environmental stress physiology, seed germination, dormancy and stomata function and transpiration, both parts of plant water relations, are studied by plant physiologists.
Famous quotes containing the words plant and/or physiology:
“I wish that friendship should have feet, as well as eyes and eloquence. It must plant itself on the ground, before it vaults over the moon. I wish it to be a little of a citizen, before it is quite a cherub.”
—Ralph Waldo Emerson (18031882)
“Now the twitching stops. Now you are still. We are through with physiology and theology, physics begins.”
—Alfred Döblin (18781957)
