Many plants are able to move their leaves slowly to keep them facing the sunlight. In same plants, this movement is very fast. The sensitive plant suddenly collapses all its leaves when touched, and looks as though it is dead. This is to help protect it from grazing animals. Other forms of movement happen when a plant distributes its seeds. Some plants can ‘fire’ their seeds for a considerable distance, making sure that the new plants do not grow too close.
