  • Explain gravitropism as a plant response where certain parts grow towards or away from gravitational pull.
  • Explain phototropism as a plant response where certain parts grow towards or away from the light source.
  • Conduct an investigation and describe the processes of gravitropism and phototropism in both shoots and roots.
  • Clarify how phototropism and gravitropism in shoots serve as examples of chemical regulation in plant growth.
  • Describe the function of auxin in regulating shoot growth, focusing on: (a) its production in the shoot tip, (b) its diffusion throughout the plant from the shoot tip, (c) its uneven distribution in response to light and gravity, and (d) its role in promoting cell elongation.
