Detailed explanation-1: -For instance, plants generally direct root growth down into the soil (gravitropism) to help anchor the plant and absorb water (hydrotropism) and nutrients while directing shoot growth upward toward a source of light (phototropism; Molas and Kiss, 2009 and heliotropism; Vandenbrink et al., 2014).
Detailed explanation-2: -Phototropism and gravitropism act together in nature to confer adaptive growth movements to plants. Light influences gravitropic responses, and concomitantly, gravity affects light responses (Hangarter, 1997).
Detailed explanation-3: -Advantages of gravitropism in roots It allows the root to anchor strongly into the soil. This allows the plant to stay erect and bear environmental pressure. This allows other tropisms like phototropism to interact evidently with the plant growth. This also allows the plant to search for water.
