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 grow savager and savager every day, as if fed on raw meat, and my tameness is only the repose of untamableness. I dream of looking abroad summer and winter, with free gaze, from some mountain-side,... to be nature looking into nature with such easy sympathy as the blue-eyed grass in the meadow looks in the face of the sky. From some such recess I would put forth sublime thoughts daily, as the plant puts forth leaves.”
—Henry David Thoreau (1817–1862)
“The world moves, but we seem to move with it. When I studied physiology before ... there were two hundred and eight bones in the body. Now there are two hundred and thirty- eight.”
—Ellen Henrietta Swallow Richards (1842–1911)
