Botanical families are groups of related plants that share common characteristics and genetic traits. Each family includes various species that may have similar flowers, leaves, or growth habits. For example, the Rosaceae family includes roses, strawberries, and apples, all of which exhibit certain botanical features that link them together. Scientists classify plants into families to better understand their relationships and evolution. This classification helps in identifying plants and studying their uses in areas like medicine, agriculture, and horticulture. The Asteraceae family, for instance, includes sunflowers and daisies, showcasing the diversity within a single family.
