Botany is a natural science concerned with the study of plants.The main branches of botany (also referred to as "plant science") are commonly divided into three groups: core topics, concerned with the study of the fundamental natural phenomena and processes of plant life, the classification and description of plant diversity; applied topics which study the ways in which plants may be used for ...
Flower production and trade supports developing economies through their availability as a fair trade product. [140] View of the Tampere Central Square during the Tampere Floral Festival in July 2007. Flowers provide less food than other major plant parts (seeds, fruits, roots, stems and leaves), but still provide several important vegetables ...
In another legume, soybeans, the flowers open and remain receptive to insect cross pollination during the day. If this is not accomplished, the flowers self-pollinate as they are closing. Among other plants that can self-pollinate are many kinds of orchids, peas, sunflowers and tridax. Most of the self-pollinating plants have small, relatively ...
Flowering plants are plants that bear flowers and fruits, and form the clade Angiospermae (/ ˌ æ n dʒ i ə ˈ s p ər m iː /). [5] [6] The term 'angiosperm' is derived from the Greek words ἀγγεῖον / angeion ('container, vessel') and σπέρμα / sperma ('seed'), meaning that the seeds are enclosed within a fruit.
Self-pollination occurs when pollen from one flower pollinates the same flower or other flowers of the same individual. [45] It is thought to have evolved under conditions when pollinators were not reliable vectors for pollen transport, and is most often seen in short-lived annual species and plants that colonize new locations.

Floral biology is an area of ecological research that studies the evolutionary factors that have moulded the structures, behaviours and physiological aspects involved in the flowering of plants. The field is broad and interdisciplinary and involves research requiring expertise from multiple disciplines that can include botany, ethology ...
The word "flora" comes from the Latin name of Flora, the goddess of plants, flowers, and fertility in Roman mythology. [5] [6] The technical term "flora" is then derived from a metonymy of this goddess at the end of the sixteenth century.
