flower : : the specialized part of an angiospermous plant that occurs singly or in clusters, possesses whorls of often colorful petals or sepals, and bears the reproductive structures (such as stamens or pistils) involved in the development of seeds and fruit : blossom — Webster
Flower, sometimes known as a bloom or blossom, is the reproductive structure found in plants that are floral (plants of the division Magnoliophyta, also called angiosperms). The biological function of a flower is to effect reproduction, usually by providing a mechanism for the union of sperm with eggs. Flowers may facilitate outcrossing (fusion of sperm and eggs from different individuals in a population) or allow selfing (fusion of sperm and egg from the same flower). Some flowers produce diaspores without fertilization (parthenocarpy). Flowers contain sporangia and are the site where gametophytes develop. Many flowers have evolved to be attractive to animals, so as to cause them to be vectors for the transfer of pollen. After fertilization, the ovary of the flower develops into fruit containing seeds. In addition to facilitating the reproduction of flowering plants, flowers have long been admired and used by humans to beautify their environment, and also as objects of romance, ritual, religion, medicine and as a source of food. — Wikipedia

Genome analysis reveals that North African date palms are a hybrid between cultivated date palms from the Middle East and a different, wild species of palm that grows on the island of Crete and in small areas of Southern Turkey. These findings, the result of research at NYU Abu Dhabi's Center for Genomics and Systems Biology (NYUAD CGSB), shed new light on the evolutionary history of one of the earliest domesticated tree crops in the world, which remains a major fruit crop in North Africa and […]

Given the pressures that pollinators face in agricultural land, cities could play an important role in conserving pollinators, according to a new study. The research, carried out by scientists at the Universities of Bristol, Edinburgh, Leeds and Reading in collaboration with Cardiff University and the National Socio-Environmental Synthesis Center (SESYNC), has revealed that gardens and allotments are good for pollinators, and lavender and borage are important garden plants that pollinators use […]
