Yes, such movemnets are called nastic movements. Nastic movement is a plant movement that is caused by an external stimulus, such as light or temperature, but is directionally independent of its source.
Examples - The opening and closing of crocus flowers following an increase or decrease in temperature, the opening and closing of evening primrose Oenothera flowers on exposure to dark and light and the leaf movements of the Venus flytrap Dionaea muscipula following a tactile stimulus.
