Question

explain giving reason the bending of root tip of a plant toward Earth

I need a short answer with full explanation .....!!!​

Answer 1

Answer:

its because of geotropism.the shoots always grow upwards against the gravitational force offered by earth.

the roots grow downwards due to the gravitational force offered by the earth

Answer 2

Answer:

The tip of a root always bends towards the earth due to gravity.

• Here, gravitational force of the earth acts as a stimulus for the plant.
• This results in the bending of tip of roots of plants towards the earth.

This is known as geotropism.

Experiment for verification:

1. Hang a plant from the ceiling as shown in figure 1.
2. In a few days, you'll observe that the roots grow towards the earth and shoot grows away from the earth as shown in figure 2.
