Here leaves starts twisting or bending in response to cold temperatures. The movement of higher plants are chiefly in the form of bending twisting and elongation of certain plant parts or organs.
How Many Types Of Nastic Movements Occur In Plants
Movement of tentacles in drosera closing of lid of nepenthes due to nitrogenous food and penetration of haustoria of parasite into host body etc.
Tropic movement in plant pdf. For instance movement of pollen tube towards ovary due to absorption of calcium and borate from style of carpel. Smaller plant organisms and naked protoplasmic bodies show movements of locomotion where as higher plants being fixed in a position show movements of curvature. For example this type of movement is usually seen in the plants of rhododendron.
Phototropism the movement of a part of the plant towards light is called phototropism. But plants can move their individual parts. Movement in plants.

Certain chemical substances are responsible to bring about curvature movements in plant organs. A tropism from greek tropos tropos a turning is a biological phenomenon indicating growth or turning movement of a biological organism usually a plant in response to an environmental stimulusin tropisms this response is dependent on the direction of the stimulus as opposed to nastic movements which are non directional responses.
