State whether true/false:
Variation movements are not unidirectional.

The given statement is true.

Variation movements are not unidirectional, which means they can occur in multiple directions. For example, in response to a stimulus, a plant may bend towards or away from the stimulus, depending on the direction and intensity of the stimulus. Similarly, the opening and closing of leaves or petals can also occur in multiple directions depending on the time of day, light intensity, or other environmental factors.
