PREAMBLE
Name one of the common signs of water stress in plants. Coming round for answers.
1. Wilting (loss of turgidity, causing leaves and stems to droop)
2. Leaf curling or rolling (reduces surface area exposed, minimizing water loss)
3. Yellowing or browning of leaves (chlorosis / leaf scorch, especially at the tips and edges)
4. Stunted growth (reduced rate of growth)
5. Premature leaf drop (abscission)
6. Reduced leaf size (smaller new leaves than normal)
