Question

What is positive geotropism?

Answer 1

Positive geotropism, also known as positive gravitropism, refers to the growth response of plants in the direction of the gravitational pull. In this process, plant roots exhibit positive geotropism by growing downward into the soil, seeking water and nutrients, while the stems and shoots typically demonstrate negative geotropism by growing upwards, away from the pull of gravity. This growth behavior is crucial for the plant's stability, nutrient acquisition, and overall health. It is part of a larger set of responses that plants exhibit toward environmental stimuli, known as tropisms.
