Plants, however, are rooted in place and must respond to the surrounding environmental factors. Plants have sophisticated systems to detect and respond to light, gravity, temperature, and physical touch. Receptors sense environmental factors and relay the information to effector systems—often through intermediate chemical messengers—to bring about plant responses.

They coordinate many responses including growth, reproduction, dormancy, and stress responses. The five major categories of plant hormones are auxins, cytokinins, gibberellins, abscisic acid, and ethylene.

Auxins regulate processes like phototropism, gravitropism, and fruit development, enhancing horticultural practices. Additionally, it covers synthetic auxins like 2,4-D and 2,4,5-T, used as selective herbicides that affect broad-leaved plants while sparing grasses, though their mechanisms are not fully understood.
