Explain

In AQA GCSE Biology, Explain means give a linked reason, mechanism, or cause-and-effect account rather than naming a fact. For Plant tissues, organs and systems, use Explain to support the objective to explain how root hair cells are adapted for absorbing water by osmosis and mineral ions by active transport. Related approved keywords for this objective include root hair cells. This definition is deliberately scoped to Plant organ system, so it preserves this concept without merging it with neighbouring key terms.
