What is the primary role of silica gel in floral preservation?

1. Enhances color

2. Absorbs moisture

3. Acts as a fertilizer

4. Improves fragrance

The correct answer is: Absorbs moisture

The primary role of silica gel in floral preservation is to absorb moisture. Silica gel is a desiccant, meaning it has the ability to draw moisture out of the air, which helps to prevent the deterioration and decay of flowers. By removing moisture, silica gel creates an environment that slows down the natural processes of wilting and decay, thus helping to maintain the aesthetic qualities of the flowers for a longer period. This use of silica gel is particularly important in techniques for drying flowers, as the effective removal of moisture is essential for preserving their shape and color. In contrast, enhancing color, acting as a fertilizer, or improving fragrance are not functions of silica gel in the context of floral preservation. These aspects relate to plant health and appearance under different conditions but do not pertain to the primary function of silica gel.
