Final answer:
Smooth leaves have a plain surface, while serrated leaves have jagged edges. Smooth leaves are common in moist environments, while serrated leaves are found in drier and windier areas. Serrated leaves help reduce water loss and increase stability.
Step-by-step explanation:
In terms of leaves, a smooth leaf has a plain, unbroken surface, while a serrated leaf has jagged, tooth-like edges. Smooth leaves are typically found in plants that grow in environments with plenty of moisture and less physical stress. They maximize the amount of light that reaches the leaf surface. Serrated leaves, on the other hand, are usually found in plants that grow in drier environments or areas with strong winds. The serrations help to reduce water loss and increase the stability of the leaf.
