Key Differences
A leaf, in botanical terms, is an integral part of a plant. It's primarily responsible for photosynthesis, converting light into energy. A leaflet, when discussed botanically, refers to the individual segments of a compound leaf, where a single leaf is divided into several smaller parts.
Beyond botany, the term leaflet takes on a different meaning. Here, a leaflet typically describes a small, flat, often folded printed piece of paper, usually used to convey information or for advertising. In comparison, the term leaf can also pertain to pages in books or other bounded materials.
Structurally, a leaf is usually attached to the stem or branch by a petiole. It can be simple (undivided) or compound (divided into leaflets). In the realm of compound leaves, each segment or division is termed a leaflet, functioning collectively as a single leaf.
When considering design and purpose, a printed leaflet is intended to be brief, conveying information succinctly. The leaf, in contrast, is nature's design for efficient energy conversion, capturing sunlight and carbon dioxide to produce energy for the plant.

Not exactly. A 'leaf' in a book consists of two pages, front and back.
How do leaves change color in the fall?
Chlorophyll breaks down, revealing other pigments in the leaf.
Can leaflets be digitally distributed?
Yes, though digital versions are often called e-leaflets or e-brochures.
Are leaflets in plants always smaller than leaves?
Typically, yes. Leaflets make up segments of a larger compound leaf.
What's the primary function of a leaflet in a compound leaf?
A leaflet performs photosynthesis just as a whole leaf would.
Is every segment of a compound leaf called a leaflet?
Yes, individual segments of a compound leaf are called leaflets.
Can leaflets be used for advertising purposes?
Yes, leaflets are often used for advertising or disseminating information.
