How do plants respond to gravitropism
WebMay 8, 2024 · Gravitropism, also known as geotropism, is the plant's response to gravity. It is the reason why the roots of the plant grow in the opposite direction from its stem. If you … WebApr 7, 2024 · Plants can respond to several different aspects of their environments. These include gravity, water, light and contact with objects. Gravitropism Plant parts tend to either grow in the same direction as gravity, or in the opposite direction. This type of tropism is called gravitropism.

WebAug 1, 2024 · Tropisms are directed growth-mediated plant movements which allow plants to respond to their environment. Gravitropism is the ability of plants to perceive and respond to the gravity vector and orient themselves accordingly. The gravitropic pathway can be divided into three main components: perception, biochemical signaling, and differential ...
