Features of the Flowers
Features of the Flowers are:
- Composite structure: Asteraceae flowers are composed of numerous individual flowers grouped together into a dense head, called a capitulum or flower head.
- Two types of florets: The flower head contains two types of florets – ray florets and disk florets. Ray florets are located on the periphery and typically have elongated petals, while disk florets are found in the central disk and have tubular structures.
- Inflorescence arrangement: Flower heads are arranged in various inflorescence types, including solitary heads, corymbs, panicles, and spikes, depending on the species.
- Modified leaves: Each flower head is surrounded by a whorl of modified leaves called phyllaries, which protect the developing flowers and give the head its characteristic shape and appearance.
- Color and shape variation: Asteraceae flowers exhibit a wide range of colors, including white, yellow, orange, pink, and purple, and may vary in shape from daisy-like to button-like, depending on the species.
- Reproductive structures: Each individual flower within the head consists of reproductive structures, including stamens (male reproductive organs) and pistils (female reproductive organs), enclosed within the floral tube.
- Pollination mechanisms: Asteraceae flowers attract a diverse range of pollinators, including bees, butterflies, moths, beetles, and flies, through the production of nectar, fragrance, and bright colors.
Asteraceae – Angiosperm Family
Asteraceae, commonly known as the aster, daisy, or sunflower family, is one of the largest plant families characterized by composite flower heads and alternate leaves. It includes a wide variety of economically important plants, such as sunflowers, daisies, and dandelions. Members of this family are used for food (lettuce, artichokes), medicine (chamomile, arnica), and ornamental purposes. Their ecological importance lies in providing nectar and habitat for pollinators, contributing to biodiversity and ecosystem health.
