Question

Name the part of the plant that shows the positive geotropism and why

Answer 1

Answer:

Root is the part of plant which show positive geotropism

Explanation: geotropism means movement towards the gravity therefore root is the part which grows downwards

Answer 2

Answer:

Geotropism is the influence of gravity on plant growth or movement. Simply put, this means that roots grow down and stems grow up. Geotropism comes from two words, “geo” which means earth or ground and “tropism” which means a plant movement triggered by a stimulus.

In this case, the stimulus is gravity. The roots are the part of plant which shows positive geotropism. Upward growth of plant parts, against gravity, is called negative geotropism, and downward growth of roots is called positive geotropism.

Extra info : In plant roots, the very end of the root is called the root cap. It makes the roots turn downward as they grow. The root cap is vital for geotropism since it contains cells with sensors called statoliths.

Hope this helps!
