Biology Glossary

ethene

In Control and coordination, ethene means a plant hormone that regulates processes including fruit ripening and cell division. This matters in Plant hormones (biology only) because it supports the learning objective to state (HT only) that the detailed mechanisms of gibberellin and ethene action are not required. Use ethene 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.
