Worked Solution & Example Answer:How does a plant respond in order to keep cool on an extremely hot day? (A) It grows smaller leaves - HSC - SSCE Biology - Question 18 - 2012 - Paper 1
Step 1
It opens stomata in the leaves.
Answer
On extremely hot days, plants often open their stomata to allow for increased transpiration. This process helps in cooling the plant by releasing water vapor, which cools the leaves and the surrounding air through evaporative cooling. This response is crucial for maintaining suitable internal temperatures and preventing overheating.
