  • Phototropism – Definition and Steps With Diagram - Science Facts
    ‘Photo’ means light, and ‘tropism’ means turning Phototropism is the movement of plants or other organisms, such as fungi, in the direction of light or away from it
  • Phototropism - Definition, Examples and Quiz - Biology Dictionary
    Phototropism is the ability of a plant, or other photosynthesizing organism, to grow directionally in response to a light source Plants and other autotrophs need to manufacture their own food; they usually do this through photosynthesis
  • Phototropism – Definition, Types, Mechanism, Importance, Examples
