The time-honored method of preserving flowers and leaves by flattening them is called what?

• A. Air drying
• B. Pressing
• C. Freeze-drying
• D. Silica gel drying

Answer: (B)

Pressing is the traditional method of preserving flowers and leaves by flattening them between sheets and applying weight. This gentle compression dries the plant material while keeping it in a thin, flat sheet, which makes it ideal for mounting, cards, and herbarium-style displays. The flattening aspect is what distinguishes this method from others: air drying dries the material without compression (often leaving curling or warping), freeze-drying preserves more of a three-dimensional shape with minimal flattening, and silica gel drying speeds moisture loss but doesn’t inherently flatten the specimen. So the term that describes preserving by flattening is pressing.
