Glycerin is used to preserve which elements?

• A. Evergreens and some flowers; odorless, colorless, syrupy liquid
• B. Fruits
• C. Water
• D. Soil

Answer: (A)

Glycerin preservation works by letting glycerin be taken up by plant tissues, replacing the water inside the cells. This keeps the cells hydrated enough to stay soft and flexible, so the foliage and treated flowers don’t become brittle like dried materials. Evergreen foliage is especially well-suited to this method because its leaves readily absorb glycerin, resulting in a pliable, lifelike material that can last much longer in arrangements. Other materials, like fruits, aren’t preserved this way, and glycerin isn’t used to preserve water or soil. The technique is aimed at creating long-lasting greenery with a natural look and feel.
