A young dicot seedling (e.g soyabean) is subjected to gravity stimulus by laying it horizontally on a surface the shoot bends upwards and root bends downward. Indicate the reason.
1
Redistribution of auxin throughout the seedlings is responsible for stimulatory unequal growth in shoots and roots.
2
Redistribution of auxin in shoots while cytokinin in roots is responsible for stimulatory unequal growth.
3
Redistribution of auxin in roots while cytokinin in shoots is responsible for stimulatory unequal growth.
