What is a distinctive feature of marijuana leaves?

Marijuana leaves are characterized by their unique structure, which typically includes pointed tips at both ends. This pointed appearance is prominent in the various strains of cannabis, reflecting the plant's genetic diversity. The shape of the leaves plays a vital role in their ability to photosynthesize effectively, maximizing sunlight absorption.

The other options do not accurately describe the typical features of marijuana leaves. For example, marijuana leaves typically have an odd number of leaflets due to their palmate structure, meaning they will not have an even number of leaves. While some strains may exhibit round or serrated leaves, the defining characteristic recognized by most is the pointed tips, which are a signature of the plant. Thus, the pointed ends are a distinctive feature that helps in identifying marijuana leaves.
