Which option correctly changes the wrong statement that plants are only passive?

Answer and explanation

Correct answer: Plants can respond to light, water, gravity, touch, and chemicals

Plants lack an animal-like brain and nervous system, but they are not passive. They detect environmental stimuli and coordinate responses through chemical signals, changes in growth, and rapid changes in cell water content. Phototropism, hydrotropism, gravitropism, thigmotropism, and chemotropism illustrate this ability. Therefore option A is correct; the other options deny plant sensitivity or incorrectly impose animal structures and blood-based control on plants.
