Explanation:
Detailed explanation-1: -The effect of gravity on the direction of plant growth is called gravitropism. (The effect of gravity on plant growth is often called geotropism because the Earth itself (geo) is responsible for the stimulus.
Detailed explanation-2: -So if the root bends when the root’s like this, these tiny bodies are called statoliths. And this somehow sends a signal to the cell and then to the root that it’s vertically oriented and that it should keep growing down.
Detailed explanation-3: -Thigmotropism is a directional growth movement which occurs as a mechanosensory response to a touch stimulus.
