Single Floret of the Bidens laevis (Brook Sunflower)
Single Floret of the Bidens laevis (Brook Sunflower)
This single floret is one of multiple disk flowers that make up the dense head in the center of the Bidens laevis, a member of the Aseraceae family. It is a composite flower that is very similar to the sunflower that we dissected in class under the microscope. I have grown sunflowers like the Bidens laevis for many years but never realized until now that the center mass is the reproductive center composed of many tiny tubular florets like this one. At the top of the floret is the stigma where pollen is deposited by the birds and bees that are looking for the sweet nectar concealed in the florets and are lured by the bright yellow but sterile ray flowers that surround the florets. These daisy-like angiosperms are dicots and considered highly evolved because there are so many disk florets which help ensure fertilization and subsequent germination of the seeds that develop in the ovaries. The seeds also cling to the fur of animals and clothing of humans which means that they are also widely distributed. The Bidens laevis is a native of California and the southern half of the U.S. It is often found in wetland areas and can be invasive.
A flower, sometimes known as a bloom or blossom, is the reproductive structure found in flowering plants (plants of the division Magnoliophyta, also called angiosperms). The biological function of a flower is to mediate the union of male sperm with female ovum in order to produce seeds. The process begins with pollination, is followed by fertilization, leading to the formation and dispersal of the seeds. For the higher plants, seeds are the next generation, and serve as the primary means by which individuals of a species are dispersed across the landscape. The grouping of flowers on a plant are called the inflorescence. In addition to serving as the reproductive organs of flowering plants, flowers have long been admired and used by humans, mainly to beautify their environment but also as a source of food.
