Vedclass · Answer

(D) $Desmodium$ $gyrans$ (also known as the telegraph plant) exhibits autonomous movements of its lateral leaflets. These movements are rhythmic and jerky,driven by changes in turgor pressure within the pulvinus cells at the base of the leaflets. These movements are not induced by external stimuli like gravity (geotropism) or water (hydrotropism). Therefore,they are classified as autonomous or spontaneous movements,not tropic movements. Thus,the correct answer is $D$.
