Rice plants often grow in flooded paddy fields where the roots are submerged in water. Describe how rice plants are adapted to survive these waterlogged conditions, including the roles of aerenchyma and ethanol fermentation.

Energy and respiration: describe question
How this question is marked
5 marks, so the mark scheme is looking for about 5 separate creditworthy points. Making the same point twice in different words earns it once.
Describe means: Say what happens or what something is like, in order and with detail. You are not being asked why. If there is data, quote it: name the trend, then give figures with units at the points where it changes.
