Which family features plants known for producing flower heads with small tube-like flowers?

The family known for producing flower heads with small tube-like flowers is Asteraceae. This family, often referred to as the daisy or composite family, is characterized by its unique flower structure, where what appears to be a single flower is actually a cluster of many tiny flowers called florets. In Asteraceae, these florets can be tubular and are typically surrounded by bracts, which together form a dense flower head, also known as a capitulum. This arrangement allows for an efficient pollination mechanism, attracting a wide range of pollinators.

Plants within the Asteraceae family, such as sunflowers, daisies, and chrysanthemums, not only display this morphological trait but also show great diversity in their ecological roles and habitats. The distinctive characteristics of Asteraceae, particularly the composite flower structure, are what set them apart from other plant families.
