In a mature flower, the perianth consists of a calyx and the corolla (petals) it supports. Petals are modified leaves that form an inner whorl surrounding the reproductive parts of flowers. They are often brightly coloured or unusually shaped to attract pollinators. All of the petals of a flower are collectively known as the corolla.
Distinct petals and sepals would therefore have arisen by differentiation, probably in response to animal pollination. In typical modern flowers, the outer or enclosing whorl of organs forms sepals, specialised for protection of the flower bud as it develops, while the inner whorl forms petals, which attract pollinators .
A mature flower. In this example, the perianth is separated into a calyx (sepals) and corolla (petals) The perianth (perigonium, perigon or perigone in monocots) is the non-reproductive part of the flower, and structure that forms an envelope surrounding the sexual organs, consisting of the calyx (sepals) and the corolla (petals) or tepals when called a perigone.
The flowers are produced on stalks 3–10 cm (1–4 in) long, and have eight creamy white petals – hence the specific epithet octopetala. [4] The style is persistent on the fruit with white feathery hairs, functioning as a wind-dispersal agent. The feathery hairs of the seed head first appear twisted together and glossy before spreading out ...
Diagram of flower parts. In botany, floral morphology is the study of the diversity of forms and structures presented by the flower, which, by definition, is a branch of limited growth that bears the modified leaves responsible for reproduction and protection of the gametes, called floral pieces.
The name "Anthozoa" comes from the Greek words άνθος (ánthos; "flower") and ζώα (zóa; "animals"), hence ανθόζωα (anthozoa) = "flower animals", a reference to the floral appearance of their perennial polyp stage. [1] Anthozoans are exclusively marine, and include sea anemones, stony corals, soft corals, sea pens, sea fans and ...
The art of the Middle Ages was mainly religious, reflecting the relationship between God and man, created in His image. The animal often appears confronted or dominated by man, but a second current of thought stemming from Saint Paul and Aristotle, which developed from the 12th century onwards, includes animals and humans in the same community of living creatures.
