Question

Differentiate between positive and negative geotropism with the help of an activity.

Answer 1

Answer:

Explanation:The growth of plant roots is an example of geotropism. (b) If the movement of the plant parts is towards the pull of gravity, it is known as positive geotropism; whereas if the movement of the plant parts is in the direction opposite to the pull of gravity, it is known as negative geotropism.

Answer 2

Answer:

Geotropism is the property by which, roots of a plant have a tendency to grow in the direction  of the earth.

Explanation:

Keep a potted plant near the window in a dark room for a few days. Observe that the

stem of the plant has bent towards the source of light and the roots away from light, in the direction

of the earth. Thus the roots show positive geotropism and the stem shows negative geotropism.
