Question

environmental factors quick check
the stem of a plant is growing upward while the roots grow downward. which of these stimuli correctly describes the response of the plant? (1 point)
○ light
○ temperature
○ gravity
○ touch

Explanation:

This plant response, where stems grow upward and roots grow downward relative to the Earth's pull, is a directional growth called gravitropism, triggered by gravity. Light causes phototropism, temperature affects growth rate, and touch triggers thigmotropism, which do not match this specific up/down growth pattern.

Answer:

gravity
