describe the shape and arrangemnt of sunflower
Answers
Answer:
With its strong stature, its giant round shape and its brilliant yellow color, the sunflower truly looks like a droplet of golden sun. It's no wonder its proper name, Helianthus anuus, comes from the Greek words “helios” (or “sun”) and “anthos” (or “flower”).Sunflowers, which belong to the daisy family, usually have 55, 89 or 144 petals, and spiral patterns are evident in their seeds. Biologists described long ago how the phylla are arranged, but explaining why these patterns form is much more difficult, and it is only recently that real progress has been made.
Answer:
The common sunflower (H. annuus) is an annual herb with a rough hairy stem 1–4.5 metres (3–15 feet) high and broad, coarsely toothed, rough leaves 7.5–30 cm (3–12 inches) long arranged in spirals. The attractive heads of flowers are 7.5–15 cm wide in wild specimens and often 30 cm or more in cultivated types.
