Final answer:
Plants growing in sunlight tend to have smaller leaves compared to plants growing in shade. This is due to adaptations to reduce transpiration and conserve water. Hence, C) is correct.
Step-by-step explanation:
Plants growing in sunlight tend to have smaller leaves compared to plants growing in shade. This is because leaves in sunlight are more exposed to the intense heat and light, which can lead to excessive water loss through transpiration.
To reduce transpiration and conserve water, plants growing in sunlight often have smaller leaves with sunken stomata and reduced foliage. These adaptations help the plants thrive in sunny environments.
