In Lab Girl, Hope Jahren describes flowers as being “a platform of petals surrounding the ‘male’ and ‘female’ parts” (202). Indeed, flowers play a fundamental role in plant reproduction and pollination. As an abundantly diverse species, they can be found in various habitats ranging from the Mojave Desert to the Everglades. Overall, a single flower, as beautiful and common as it may be, has the ability to lure insects, produce seeds, and ultimately facilitate new plant life.
Flowers —also considered as blooms or blossoms— are the reproductive system of angiosperms: plants that produce seeds. (U. 2002). These conspicuous plant parts consist of three major components the perianth, the androecium, and the gynoecium. The perianth or the floral …show more content…

Flowers that have all of their floral parts: sepals, petals, stamen, and pistil are known as complete flowers. Subsequently flowers which lack one or more of their parts are known as incomplete flowers. In the cases involving symmetry, a flower is considered regular if its whorls are symmetrical and irregular if it is unsymmetrical. According to their sexes, a plant is considered perfect if it has both the male and female reproductive system and imperfect if it only has one reproductive system. Lastly if a flower has numerous sepals, petals, stamens and pistils, it is considered as simple. A compound flower is thus a flower that has a more reduced number of each floral organ.
According to The Editors of Encyclopædia Britannica, flowers, regardless of their diversity, all have a sole function; to reproduce (2017). There are two main organs that are involved in reproduction: the stamens and pistils. The stamen has spore cases (microsporangia) in which numerous microspores (potential pollen grains) can be developed. Fertilization can only occur through pollination; when the pollen grains from the anther is transferred to the stigma of a pistil. The two main types of pollination are self pollination and cross pollination. Self pollination also referred to as autogamy, is when a flower can fertilize itself because it has both female and male reproductive system. The most common type of pollination, however, is cross pollination. In cross pollination, a flower is
