560629656Auxin more on shaded side __ growth.more
560629657Gravitropism, which why does plant grow if it has negative gravitropism?negative means grows upwards positive means grows downwards
560629658Thigmotropism?touch EX. climbing plants
560629659Photoperiodismresponse due to change in photoperioid (length of day and night)
560629660What will a flash of red light during the night do to a plant?it will reset the plant's clock (photoperiod)
560629661Does brief period of darkness during the day have any effect on plants?no
