Answer 1

Answer:

Geotropism- The growth of the parts of plants in response to the force of gravity. The upward growth of plant shoots is an instance of negative geotropism; the downward growth of roots is positive geotropism.

Chemotropism is known as growth or movement of a complete plant or plant parts towards the chemical stimulus. For example the growth of pollen tube down to the ovule in the ovary through the stigma and style during fertilization in order to respond to the presence of sugars in the style.

Phototropism: It is the direction of growth of a plant in response to the direction of the light. Eg - Movement of shoot of plant upwards towards light.
