Structures composed of specialized tissues designed to perform specific functions in plants are referred to as what?

1. Roots

2. Stems

3. Organs

4. Leaves

The correct answer is: Organs

The term that refers to structures in plants composed of specialized tissues that perform specific functions is "organs." In botanical terminology, an organ is a combination of tissues that work together to achieve a particular task. For example, roots anchor the plant and absorb water and nutrients, stems provide support and transport, and leaves are responsible for photosynthesis. However, when considering the broader context, the collective term "organs" encompasses the various structures, including roots, stems, and leaves, all of which serve distinct and necessary functions within the plant system. Understanding this classification is important for appreciating how plants operate as complex systems.
