Detailed explanation-1: -Plant shoots tend to grow upward against the pull of gravity and so can be described as being negatively gravitropic, which is important for the parts of the plant that need to seek light for photosynthesis.

Detailed explanation-2: -Well, It is a phenomenon that is called “Gravitropism". Gravitropism is either positive which means “with gravity” or negative gravitropism which means against gravity. It is said that plant and fungi both have negative gravitropism i.e. both of them grow upwards.

Detailed explanation-3: -Many different explanations have been proposed for why plant shoots grow “up” and roots grow “down.” (The growth of roots downward, in the direction of the pull of gravity, is called positive gravitropism and the growth of shoots upward, away from the pull of gravity, is called negative gravitropism.

Detailed explanation-4: -Geotropism is a type of tropism where plants show some growth in response to gravity. Roots growing downwards is an example of geotropism.

Detailed explanation-5: -Geotropism-The movement of the plant in response to the gravity, they will move in the direction of gravity. The roots will grow downwards and show positive geotropism while shoot will grow upwards and thus show negative geotropism.
