\n1. Movement of Locomotion is one in which there is displacement. It is seen in lower plants like Algae (Chlamydomonas). This movement of locomotion may be of two types: \nA. Autonomous, if it is taking place without the involvement of any external inducer or stimulus. \nB. Paratonic, if it is taking place with some stimulus. This movement in the plant is called the Tactic movement or Taxis. \n2. Movement of curvature (or growth) is one that does not involve displacement. This is of two types: \nA. Autonomous, if it is taking place without any external stimulus. This type of movement takes place by some cellular activity, without any apparent cause and some internal stimuli are involved. The opening of the flower bud is an autonomic movement that occurs due to an internal stimulus. \nB. Paratonic, if it is taking place due to some external stimulus. There are of two types: \nI. Directional movement is called tropic movement, which is controlled by the direction of the external stimulus. An example includes the thigmotropic movement, which is directed by the touch of an object. Tendrils coil around the hard support is an example of thigmotropic movement. \nII. Non-directional movement is called nastic movement, which is not controlled by the directions of external stimuli. An example is nyctinasty, induced by the rhythm of day and night.
