Vedclass · Answer

(A) Sleep movements,also known as $nyctinasty$,are rhythmic movements of plant parts (like leaves or petals) in response to the daily rhythm of light and darkness. These movements are most commonly observed in the family $Leguminosae$ (also known as $Fabaceae$). For example,the leaves of plants like $Mimosa$ $pudica$ (touch-me-not) and various species of $Acacia$ fold up at night. This phenomenon is regulated by changes in turgor pressure within the specialized cells called $pulvini$ located at the base of the leaflets.
