Botanical structures refer to the various parts of plants that contribute to their growth, reproduction, and survival. Key structures include roots, stems, leaves, flowers, and fruits. Roots anchor the plant and absorb water and nutrients from the soil. Stems support the plant and transport substances between roots and leaves. Leaves are essential for photosynthesis, the process by which plants convert sunlight into energy. Flowers are the reproductive structures that facilitate pollination, while fruits protect seeds and aid in their dispersal. Understanding these structures helps in studying plant biology and ecology, including the roles of photosynthesis and pollination.
