coordinate cell elongation and light-seeking behavior (phototropism). Ethylene triggers fruit ripening and leaf drop.
The Symphony of Survival: Plant Physiology and Biochemistry Plant physiology and biochemistry are the twin engines driving the life of every botanical organism on Earth. While physiology focuses on the large-scale functions—how a plant grows, breathes, and reproduces—biochemistry examines the molecular machinery that makes these processes possible. Together, they explain how a stationary organism can thrive in a constantly changing environment. The Solar Engine: Photosynthesis PLANT PHYSIOLOGY and BIOCHEMISTRY
