Step-by-step explanation:
Plants respond to various components of their environment such as air, light, water, and soil. They have sophisticated systems to detect and respond to light, gravity, temperature, and physical touch. Receptors sense these environmental factors and relay the information to effector systems to bring about plant responses.
