In which direction do roots usually grow?
Answer and explanation
Correct answer: In the direction of gravity
The governing concept is geotropism, also called gravitropism. Roots usually grow downward, in the direction of the gravitational pull, so they show positive geotropism or positive gravitropism. This direction helps roots anchor the plant and reach soil resources. Therefore, option B is correct. Growth against gravity is negative geotropism and is more typical of shoots; roots generally do not grow toward light or upward.
