Describe phototropism as a plant growth response to light.

In the subtopic Control and coordination, this learning objective focuses on describe phototropism as a plant growth response to light. Within Plant hormones (biology only), students should explain this idea in the exact curriculum context rather than as an isolated fact. Approved keywords for this objective include light and phototropism. phototropism means a growth response in plants where they bend or grow towards light. Avoid students often confuse phototropism with gravitropism, thinking both responses are triggered by light; instead clarify that phototropism specifically refers to growth in response to light, while gravitropism refers to growth in response to gravity. Use diagrams to illustrate the differences. For exam answers, review how plants bend towards light and the role of auxin in this process.
