Biology Glossary

ethene

In Control and coordination, ethene means a plant hormone that regulates cell division and is involved in the ripening of fruits. This matters in Plant hormones (biology only) because it supports the learning objective to explain (HT only) that ethene controls cell division and fruit ripening. 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.
