In the absence of muscle cells, how do plant cells show movement ?

Explanation

The ability of a plant to detect change and respond to that change is termed as the sensitivity of the plant. Yet plants have no nervous system and no muscle tissue, they use electrical and chemical means to convey the information from one cell to another cell. The leaces of the sensitive plant (Misosa pudica) folds up in response to touch.
These leaf movements are independent of growth whereas, the directional movement of the shoot of a germinating seedling breaking through the soil is growth dependent.
