Make corrections wherever you find mistake in spellings/words in the following parapraphs/sentences. (A) During the period of senescence, a gradual addition occurs in the structure and functioning of an organ or organism which is characterised by the accumulation of active metabolic materials and increase in dry weight. (B) When the movement of curvature is produced by diffused stimuli and affects the whole plant uniformly, it is of tropic type. If the curvature is produced by directional mutimuli and does not affect the whole plant, it is of nastic type.
