The correct environment of air, mineral nutrients and water directs plant roots to grow in any direction to meet the plant's needs. Roots will shy or shrink away from dry [22] or other poor soil conditions. Gravitropism directs roots to grow downward at germination, the growth mechanism of plants that also causes the shoot to grow upward. [23]
