Question

What is geotropism? Draw a labelled diagram of a potted plant showing positive geotropism and negative geotropism

Answer 1

geotropism is the attraction of a plant towards the earth

Answer 2

Geotropism is the impact of gravity on plant germination or movement. This implies that roots spread downwards and stems arise up. Geotropism arises from two words, “geo” which signifies earth or ground and “tropism” which implies a plant movement triggered by a stimulus. In this instance, the stimulus is gravity. The upward extension and growth of plant parts, opposite gravity, is described as negative geotropism, and downward growth and development of roots is described as positive geotropism.
