|
|
The roots change into branches, and the branches turn into roots.
|
|
|
The roots grow toward the force of gravity, and the shoots grow away.
|
|
|
The plant will become a smaller version of a mature plant.
|
|
|
Roots always grow toward the dark, and shoots grow toward the light.

Detailed explanation-1: -seeds that are planted upside down are still able to grow into mature plants, which explanation best explains this phenomenon. Now this phenomenon is best explained by the force of gravity, so the root goes towards the force of gravity while this team goes away.
Detailed explanation-2: -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-3: -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 growth.
Detailed explanation-4: -A plant’s response to gravity is called gravitropism. This is sometimes also called geotropism and describes the ability of plant parts to grow towards or away from the earth.
Detailed explanation-5: -The roots grown downward in the direction of gravity, which is positive gravitropism, and the shoot grows upward away from gravity, which is negative gravitropism. The reason plants know which way to grow in response to gravity is due to amyloplasts in the plants.
