In which condition will small leaves benefit plants more than broad leaves?
Answer and explanation
Correct answer: A hot, dry region with low rainfall and high temperature
In hot, dry regions, water is scarce and transpiration can be high. Small leaves generally have less surface area, so they reduce water loss and help plants survive dry conditions. In humid regions such as rainforests, broad leaves can be more useful for capturing light. Exam tip: associate dry climates with small leaves and reduced transpiration.
