A plant's response to a gravitational stimuli is...

• Gravitropism

• Phototropism

• Auxin

• Thigmotropism

Auxin is a plant hormone that...

• promotes cell division in plant roots

• is responsible for the development of seed formation

•  influences stress responses throughout the plant cycle

• causes the elongation of cells: helps the regulation of plant growth
