What is the role of Auxin in plants?

• Cell elongation (tropisms)

• Cell division & growth

• Fruit ripening

• Transported in vascular tissue and affects seed growth

Which hormone is responsible for fruit ripening in plants?

• Auxin

• Cytokinin

• Ethylene

• Gibberellins

What is the function of Gibberellins in plants?

• Cell elongation (tropisms)

• Cell division & growth

• Fruit ripening

• Transported in vascular tissue and affects seed growth

What is the role of Cytokinin in plants?

• Cell elongation (tropisms)

• Cell division & growth

• Fruit ripening

• Transported in vascular tissue and affects seed growth

What happens to a plant when one side of the shoot is in the light and the other in the shade?

• The plant grows straight up, unaffected by light.

• The side of the shoot in the shade has more auxin, so grows faster, causing the shoot to bend towards the light.

• The side of the shoot in the light grows faster, causing the shoot to bend away from the light.

• The shoot bends towards the shade due to less auxin production.
