A flower is the reproductive structure of an Angiosperm plant. Flowers have ovaries with ovules that develop into fruits with seeds. There are over 300,000 species of Angiosperms, and their flowers and fruits vary significantly. Flowers and fruits are among the most useful features for the identification of plant species and determination of their evolutionary relationships.

The hunter-gatherer ancestors of modern humans surely noticed that flowers gave rise to fruits which could be eaten. Because flowers signaled an anticipated harvest, it has been suggested that these early humans instinctively considered flowers attractive, an instinct that modern humans may also have. Many modern cultures consider flowers attractive, and scholars have been fascinated with flowers …
There are considerable differences among the flowers of the 300,000 species of Angiosperms. Botanists rely upon a large vocabulary of specialized terms to describe the parts of these various flowers. The most important morphological features of flowers are considered below. Flowers can arise from different places on a plant, depending on the species. Some flowers are terminal, meaning that a singl…
The flower originated as a structure adapted to protect ovules, which are borne naked and unprotected in the Gymnosperms, ancestors of the Angiosperms. Botanists are uncertain about which group of Gymnosperms is most closely related to the Angiosperms. Recently, examination of sexual fertilization in the different groups of Gymnosperms suggests that Angiosperms may be most closely related to the G…
Many environmental cues signal a plant to produce flowers, and light is one of the most important of these. In many species, flowering is a photoperiodic response, in that it is controlled by the length of the light and dark periods to which the plant is exposed. Some plants, such as Maryland mammoth tobacco, soybean, and hemp, are short-day plants, in that they flower in the spring and autumn whe…
