In a horizontally placed plant, the root bends downward and the stem bends upward. Which conclusion is most correct?

Answer and explanation

Correct answer: The root shows positive geotropism and the stem shows negative geotropism

The governing concept is geotropism, the growth response to gravity. The root grows in the direction of gravitational pull, so it exhibits positive geotropism. The stem grows away from that direction, so it exhibits negative geotropism. Thus option A is correct. Option B reverses the signs, while chemotropism concerns chemicals and a reflex arc is a nervous-system pathway absent from ordinary plant growth.
