Mark the centre point of the foil square and place onto the clinstat so that the centre mark faces the centre of the turntable.

Mark the centre point of the foil square and place onto the clinstat so that the centre mark faces the centre of the turntable.Start the clinstat up on a very low rotational speed. Every day or two, open the foil and ensure the paper towel is moist. Try not to disturb the bean during these checks and make sure they go back in exactly the same position each time.

Try not to disturb the bean during these checks and make sure they go back in exactly the same position each time.After 5 days or so, open the packets and observe the direction of the root which should have grown.The clinostat exterts centripetal force on the bean, creating a false gravity. Instead of the root growing in response to the Earth's gravity, it grows in response to this centripetal force and outwards from the centre of the clinostat.

Answer 2

Answer:

Explanation:

✨Because plants can sense the gravitational field of the earth.Roots are positively geotropic as they bend and grow downwards . Roots of plants are called positively geotropic, because they follow the direction of stimuli by gravity
