Growth of the stem opposite to gravity is an example of what?
Answer and explanation
Correct answer: Negative geotropism
A stem usually grows upward, whereas gravity acts downward. Growth in a direction opposite to the gravitational pull is therefore called negative geotropism, making option A correct. Positive geotropism means growth with gravity, as in roots. Hydrotropism is a response to water, thigmotropism to touch, and chemotropism to chemical substances, so those options do not fit.
