Understanding Geotropism

What is the primary focus of the video tutorial?

• Exploring the water cycle

• Understanding geotropism and its relation to phototropism

• Studying human anatomy

• Learning about animal behavior

How do shoots respond to gravity?

• They grow away from gravity

• They grow towards gravity

• They remain unaffected by gravity

• They grow sideways

What is the effect of auxins on stem cells?

• They inhibit cell growth

• They stimulate cell growth

• They cause cell death

• They have no effect

In roots, what is the effect of auxins?

• They stimulate cell growth

• They have no effect

• They inhibit cell growth

• They cause cells to shrink

What is a clinostat used for in experiments?

• To water plants automatically

• To provide light to plants

• To evenly distribute auxins

What happens to a plant on a rotating clinostat?

• It bends away from the light

• It stops growing

• It grows straight

• It bends towards the light

How do roots behave in a non-rotating clinostat?

• They bend downwards

• They stop growing

• They bend upwards

• They grow straight

What is the term for the process when cells get longer and bigger?
