Which of the following pairs describe textures in floral arrangements?

The correct answer focuses on the tactile qualities of floral materials, specifically the texture described as "rough or smooth." In floral design, textures play a vital role in the overall visual impact and emotional response of an arrangement. A rough texture may add visual interest and depth, while a smooth texture conveys elegance and simplicity. Different materials, such as the leaves of certain plants, the petals of flowers, and even the surfaces of vases or containers, contribute to these textures.

By contrast, the other options are related to different aspects of floral arrangement. The distinction between sparse and dense relates more to the volume and filling of space within an arrangement rather than texture. Bright and dull describe color intensity, which doesn’t pertain to textural characteristics. Similarly, large and small refer to size, which is again unrelated to the tactile quality of materials. Thus, the only pair that accurately describes textures is the one about roughness and smoothness.
