auxins

In Use of plant hormones (HT only), auxins means plant hormones that promote growth and are used as selective weed killers in agriculture. This matters in Plant hormones (biology only) because it supports the learning objective to describe (HT only) the use of auxins as selective weed killers. Use auxins only in this subtopic-relevant sense so the definition stays concise, curriculum-specific, and useful for AQA GCSE Biology revision. Students should use this term accurately when they explain the biology, identify symptoms, or justify an answer in GCSE Biology questions.
